The energy (U_C) 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.
Energy Stored in a Capacitor | Description, Example & Application
The amount of energy stored in a capacitor depends on its capacitance, measured in farads, and the voltage across it. The formula for calculating the energy stored in a capacitor is: E = (1/2) x C x V^2. Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.
