Steady state is the term used to describe an assembled circuit in which the current and net electric field are constant and stay approximately constant for a very long time. Circuits with uniform thickness and composition can be described as steady state if charged particles move with constant current in each section of a wire in the circuit. Circuits in the steady state do not change current as a function of time.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
After a circuit has been assembled, it can be described as steady state if it meets the following requirements:&lt;br /&gt;
* mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
* no excess charges accumulate anywhere in the circuit&lt;br /&gt;
&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below - a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;&#039;&#039;&#039;I = |q|nAv&#039;&#039;&#039;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===A Mathematical Model===&lt;br /&gt;
&lt;br /&gt;
i = electron current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
I = conventional current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
v = drift speed&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
q = charge of mobile particles&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
A = cross-sectional area of wire&lt;br /&gt;
&lt;br /&gt;
In the steady state, at each section of circuit:&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;i&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = i&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;I&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = I&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* there must be a nonzero electric field in the wire&lt;br /&gt;
:* the electric field has uniform magnitude throughout the wire&lt;br /&gt;
:* the electric field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

As a biomedical engineer, the idea of steady state circuits is surprisingly interesting to me because the process of reaching steady state in a circuit is much like the process of maintaining homeostasis in the human body.&lt;br /&gt;

&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* there must be a nonzero electric field in the wire&lt;br /&gt;
:* the electric field has uniform magnitude throughout the wire&lt;br /&gt;
:* the electric field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

Steady state is the term used to describe an assembled circuit in which the current and net electric field are constant and stay approximately constant for a very long time. Circuits with uniform thickness and composition can be described as steady state if charged particles move with constant current in each section of a wire in the circuit. Circuits in the steady state do not change current as a function of time.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
After a circuit has been assembled, it can be described as steady state if it meets the following requirements:&lt;br /&gt;
* mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
* no excess charges accumulate anywhere in the circuit&lt;br /&gt;
&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below - a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Steady state is the term used to describe an assembled circuit in which the current and net electric field are constant and stay approximately constant for a very long time. Circuits with uniform thickness and composition can be described as steady state if charged particles move with constant current in each section of a wire in the circuit. Circuits in the steady state do not change current as a function of time.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
After a circuit has been assembled, it can be described as steady state if it meets the following requirements:&lt;br /&gt;
* mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
* no excess charges accumulate anywhere in the circuit&lt;br /&gt;
&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below - a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;&#039;&#039;&#039;I = |q|nAv&#039;&#039;&#039;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===A Mathematical Model===&lt;br /&gt;
&lt;br /&gt;
i = electron current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
I = conventional current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
v = drift speed&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
q = charge of mobile particles&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
A = cross-sectional area of wire&lt;br /&gt;
&lt;br /&gt;
In the steady state, at each section of circuit:&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;i&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = i&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;I&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = I&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* there must be a nonzero electric field in the wire&lt;br /&gt;
:* the electric field has uniform magnitude throughout the wire&lt;br /&gt;
:* the electric field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* there must be a nonzero electric field in the wire&lt;br /&gt;
:* the electric field has uniform magnitude throughout the wire&lt;br /&gt;
:* the electric field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

Steady state is the term used to describe an assembled circuit in which the current and net electric field are constant and stay approximately constant for a very long time. Circuits with uniform thickness and composition can be described as steady state if charged particles move with constant current in each section of a wire in the circuit. Circuits in the steady state do not change current as a function of time.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
After a circuit has been assembled, it can be described as steady state if it meets the following requirements:&lt;br /&gt;
* mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
* no excess charges accumulate anywhere in the circuit&lt;br /&gt;
&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below - a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;

Steady state is the term used to describe an assembled circuit in which the current and net electric field are constant and stay approximately constant for a very long time. Circuits with uniform thickness and composition can be described as steady state if charged particles move with constant current in each section of a wire in the circuit. Circuits in the steady state do not change current as a function of time.&lt;br /&gt;
&lt;br /&gt;
==The Main Idea==&lt;br /&gt;
&lt;br /&gt;
After a circuit has been assembled, it can be described as steady state if it meets the following requirements:&lt;br /&gt;
* mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
* no excess charges accumulate anywhere in the circuit&lt;br /&gt;
&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below - a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;&#039;&#039;&#039;I = |q|nAv&#039;&#039;&#039;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
i = electron current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
I = conventional current&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
v = drift speed&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
q = charge of mobile particles&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
A = cross-sectional area of wire&lt;br /&gt;
&lt;br /&gt;
In the steady state, at each section of circuit:&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;i&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = i&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;div class=&amp;quot;center&amp;quot; style=&amp;quot;width: auto; margin-left: auto; margin-right: auto;&amp;quot;&amp;gt;&amp;lt;big&amp;gt;I&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt; = I&amp;lt;sub&amp;gt;out&amp;lt;/sub&amp;gt;&amp;lt;/big&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* there must be a nonzero electric field in the wire&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* the electric field has uniform magnitude throughout the wire&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
:* the electric field is parallel to the wire at every location along the wire&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

&lt;br /&gt;
Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below:&lt;br /&gt;
&lt;br /&gt;
I = |q|nAv&lt;br /&gt;
&lt;br /&gt;
a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The circuit above is an example of a circuit in the steady state.&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. And since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
-there must be an E field in the wire&lt;br /&gt;
-the E field has uniform magnitude throughout the wire&lt;br /&gt;
-the E field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state.&lt;br /&gt;

What are the mathematical equations that allow us to model this topic.  For example &amp;lt;math&amp;gt;{\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net}&amp;lt;/math&amp;gt; where &#039;&#039;&#039;p&#039;&#039;&#039; is the momentum of the system and &#039;&#039;&#039;F&#039;&#039;&#039; is the net force from the surroundings.&lt;br /&gt;
&lt;br /&gt;
===A Conceptual Understanding===&lt;br /&gt;
&lt;br /&gt;
Because mobile charges are moving (with constant drift speed) in the circuit, there must be an applied electric field inside the wire that causes the mobile charges to move. Since there is no excess charge inside the wire, the electric field must be produced from surface charges. And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;
&lt;br /&gt;
Once a circuit is described as being in the steady state, there are three things we know to be true. It is true that:&lt;br /&gt;
	-there must be a nonzero E field in the wire&lt;br /&gt;
	-the E field has uniform magnitude throughout the wire&lt;br /&gt;
	-the E field is parallel to the wire at every location along the wire&lt;br /&gt;
&lt;br /&gt;
The electric field and current inside the wire remains constant because the electric force (F = qE) acting on the mobile charged particles and allowing them to move through the circuit is canceled out by the drag force produced by the moving charged particles such that the net force is zero and thus, acceleration is zero.&lt;br /&gt;
&lt;br /&gt;
When you assume that a circuit is in steady state, you are basically assuming that the circuit has been assembled and connected for a long time (such that the current is constant). However, there is a process that occurs - when the circuit is first assembled - before the circuit reaches steady state. Let’s take a look at some examples to better understand steady state circuits.&lt;br /&gt;

-mobile charges are moving with constant drift velocity anywhere in the circuit&lt;br /&gt;
-no excess charges accumulate anywhere in the circuit&lt;br /&gt;

Although mobile charges are moving, the drift velocities of the charges do not vary with time at any location in the circuit and thus, the current is constant throughout the circuit. However, since current is also a function of the cross-sectional area and charge density (composition) of the wire - as shown by the equation for conventional current below:&lt;br /&gt;

a steady state circuit is more specifically described as one in which the current is constant in each section of a wire with uniform thickness and composition.&lt;br /&gt;

And because this electric field is responsible for moving the mobile charges inside the wire, the direction of the electric field at each location in the wire must be parallel to the wire. &lt;br /&gt;

&lt;div&gt;__NOTOC__&lt;br /&gt;
Welcome to the Georgia Tech Wiki for Intro Physics.  This resources was created so that students can contribute and curate content to help those with limited or no access to a textbook.  When reading this website, please correct any errors you may come across. If you read something that isn&#039;t clear, please consider revising it!&lt;br /&gt;
&lt;br /&gt;
Looking to make a contribution?&lt;br /&gt;
#Pick a specific topic from intro physics&lt;br /&gt;
#Add that topic, as a link to a new page, under the appropriate category listed below by editing this page.&lt;br /&gt;
#Copy and paste the default [[Template]] into your new page and start editing.&lt;br /&gt;
&lt;br /&gt;
Please remember that this is not a textbook and you are not limited to expressing your ideas with only text and equations.  Whenever possible embed: pictures, videos, diagrams, simulations, computational models (e.g. Glowscript), and whatever content you think makes learning physics easier for other students.&lt;br /&gt;
&lt;br /&gt;
== Source Material ==&lt;br /&gt;
All of the content added to this resource must be in the public domain or similar free resource.  If you are unsure about a source, contact the original author for permission. That said, there is a surprisingly large amount of introductory physics content scattered across the web.  Here is an incomplete list of intro physics resources (please update as needed).&lt;br /&gt;

&lt;br /&gt;
== Organizing Catagories ==&lt;br /&gt;
These are the broad, overarching categories, that we cover in two semester of introductory physics.  You can add subcategories or make a new category as needed.  A single topic should direct readers to a page in one of these catagories.&lt;br /&gt;
