The capacitor, generally referred to simply as its capacity to hold a charge, is denoted by the letter C. A capacitor, as the name implies, is an 'electrically charged container', a device that contains an electrical charge. The capacitor is one of electronic elements widely used in electronic equipment, and is widely applied to aspects of blocking AC, coupling, bypassing, filtering, tuning loop, energy conversion, control and the like in a circuit. A capacitor is formed between any two conductors (including wires) which are insulated and closely spaced from each other.
