What is a Capacitor and What does it do. A capacitor is an essential electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by a non-conductive material called a dielectric. When a voltage is applied across the plates, electric charge accumulates on them, creating an electric field between the plates.
