Question

what is capacitor and whats it function

Answer 1

A dielectric can be glass, ceramic, plastic film, air, paper, mica, etc. Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, a capacitor does not dissipate energy. Instead, a capacitor stores energy in the form of an electrostatic field between its plates.

Answer 2

The definition of a capacitor is a device to store an electronic charge for a short period of time that consists of two metallic plates separated by a dielectric.
