How does a capacitor store energy?
Primarily, a capacitor stores energy in the form of an electric field between its plates, which is the main form of electrical energy stored in capacitor systems. This field represents electrostatic energy stored in capacitor devices. In specific applications, the term capacitor stores energy in the form of OVV (Over Voltage Value) may come up.
How do you find the energy stored in a capacitor?
The energy (E) stored in a capacitor is given by the formula: where (C) is the capacitance (the capacitor’s ability to store charge), and (V) is the voltage across the capacitor. Imagine slowly transferring charge from one plate to the other. As you move each tiny bit of charge, you’re doing work against the electric field.
