A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.Capacitors can store electrical energy and discharge it quickly, powering things like flash bulbs and starter motors.

The effect of a capacitor is known as capacitance.While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.
A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric.The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.

Inside, the terminals connect to two metal plates separated by a non-conducting substance. When activated, a capacitor quickly releases electricity in a tiny fraction of a second.When activated, a capacitor quickly releases electricity in a tiny fraction of a second,So that’s the basic working principle of a capacitor.
