1. Battery is a source of energy for a circuit, whereas capacitor is a passive element, which draws energy from the circuit, store and release it. 2. Usually battery is a DC component, whereas capacitor is mostly used for AC applications. It is used to block DC components in circuits.
A: A capacitor, or cap, is an electronic component that can take up, store, and discharge electrical energy. Because they can do all that quickly, capacitors are used to filter or buffer any sudden changes in a circuit's voltage, smoothing the ensuing signal.back to top.: A capacitor, or cap, is an electronic component that can take up, store, and discharge electrical energy.
