Stored Energy Is Released Quickly. When a capacitor is fully charged it holds energy which we call stored energy. The stored energy in the capacitor can be delivered quickly to the component or point in the circuit where it is needed. As soon as the power source drops off the capacitor will deliver voltage from itself. Losses Are Low
Energy storage (ES) is a form of media that store some form of energy to be used at a later time.
