The capacitor, usually referred to as its capacitance, is written in the letter C. Definition 1: capacitor, as the name suggests, is an electric container, a device that holds charge. English Name: capacitor. Capacitor is one of the most widely used electronic components in electronic equipment. It is widely used in the aspects of the circuit, such as coupling, coupling, bypass, filtering, tuning circuit, energy conversion, control and so on. Definition 2: capacitor, any two insulated conductors (including conductors) which are very insulated from each other, including a conductor, form a capacitor.
