What is Energy stored in Capacitor?

The energy stored in a capacitor is electrostatic potential energy. Thus, it is 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. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.
