	The charged '''capacitor''' can be originated back to 1745 when '''Pieter van Musschenbroek''', Dutch physicist from the University of Leiden, first created the Leyden jar. This was a glass jar coated with metal foil and was designed to store static electric charge, technically making it the first '''capacitor'''. Later, '''Benjamin Franklin''' used these jars for his famous electrical experiments, which greatly advanced the field in understanding how charge accumulates and discharges. Later '''Michael Faraday''' in the 19th century was able to describe the science of capacitance in a more scientific way through introducing the concept of the dielectric constant. He was able to explain how insulating materials between the conductive plates were able to store charge. The modern definition of a '''capacitor''', C = Q/V, can be attributed to him with the Farad (F) being the SI unit of capacitance.

	There are many real world applications of charged capacitors:		There are many real world applications of charged '''capacitors''':

	Medical Devices - Defibrillators		'''Medical Devices - Defibrillators'''

	A life saving application of a charged capacitor is the cardiac defibrillator. In this device a capacitor is charged to a high voltage then discharged in milliseconds through the chest of a patient to restore and maintain normal sinus rhythm. This is done through the ability of the device to store and quickly release a precise amount of energy.		A life saving application of a charged '''capacitor''' is the cardiac defibrillator.

	Energy Storage & Power Supplies		'''Energy Storage & Power Supplies'''

	Capacitors are able to discharge electrical energy at instantaneous rates. This makes them important in power supply circuits where they smooth out the voltage fluctuations. Unlike batteries, capacitors are able to discharge their energy at microseconds giving them critical applications where rapid bursts of power are required.

	Flash Photography		'''Flash Photography'''

	The camera flash seen across many devices is an application of a classic capacitor. Once the capacitor is charged by the device battery it is able to rapidly discharge to produce a burst of light. This is important as the capacitor is able to deliver far more instantaneous power than a battery alone.		The camera flash seen across many devices is an application of a classic '''capacitor'''.

	Electric Vehicles (Supercapacitors)		'''Electric Vehicles (Supercapacitors)'''

	Supercapacitors are high capacity versions of capacitors used in both hybrid and electric vehicles. Their main purpose is to capture the energy created in regenerative braking as well as rapidly release this energy during acceleration. In addition, capacitors are able to preserve the car battery health, which would otherwise degrade under rapid charge and discharge cycles.
