The energy stored in a capacitor is electrostatic potential energy and is thus related to the charge and voltage between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Ever-increasing effort must be put in against this ever-increasing electric field as more charge is separated - work has to be done. The energy (measured in joules) stored in a capacitor is equal to the amount of work required to establish the voltage across the capacitor, and therefore the electric field.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Capacitors are potentially dangerous because they store a significant amount of energy. Short-circuiting or mishandling a charged capacitor results in a rapid discharge, causing sparks, burns, or even an electric shock. In extreme cases, large capacitors deliver a potentially lethal shock.
The amount of storage in a capacitor is determined by a property called capacitance, which you will learn more about a bit later in this section. Capacitors have applications ranging from filtering static from radio reception to energy storage in heart defibrillators.
When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. To gain insight into how this energy may be expressed (in terms of and ), consider a charged, empty, parallel-plate capacitor; that is, a capacitor without a dielectric but with a vacuum between its plates.
