			Electric Field and Electric Potential

			ELECTRIC FIELD:
			What is it??
			Electric fields and electric potentials describe how charges interact at a distance.
			The electric field (
			𝐸
			⃗
			E
			) shows the direction and strength of force on a positive test charge, while electric potential (
			𝑉
			V) represents potential energy per unit charge at a point in space.

			These two quantities are closely related:

			Electric field is vector (has direction).

			Electric potential is scalar (has magnitude only).

			The field always points in the direction of decreasing potential.

			Key Definitions

			Electric Field:

			𝐸
			⃗
			=
			𝐹
			⃗
			𝑞
			E
			=
			q
			F



			The force per unit charge. Units:
			N/C
			N/C.

			Electric Potential Energy:


			U=qV

			The work needed to bring a charge
			𝑞
			q from infinity to that point.

			Electric Potential:





			Units:
			J/C
			J/C (also known as Volts).
