A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

What Are Capacitors? Capacitors are electronic components that store and release electrical energy. They consist of two conductive plates separated by an insulating material called a dielectric.. When voltage is applied across the plates, it creates an electric field across the dielectric, allowing the capacitor to store energy.
