A capacitor stores energy by accumulating charge on its plates when connected to a power source. This makes capacitors useful in power supply filtering, signal processing, and energy. . Capacitors (sometimes known as condensers) are energy-storing devices that are widely used in televisions, radios, and other kinds of electronic equipment. A dielectric material separates the two conductive plates that jointly make a capacitor. By. . A capacitor is an electronic component that stores and releases electrical energy.
