Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
