In this article, we'll learn exactly what a capacitor is, what it does and how it's used in electronics. We'll also look at the history of the capacitor and how several people helped shape its progress.
In a circuit, a capacitor acts as a charge storage device. It stores electric charge when voltage is applied across it and releases the charge back into the circuit when needed. A basic capacitor is made of two parallel metal plates separated by a dielectric material.
A capacitor, also called a condenser, is thus essentially a sandwich of two plates of conducting material separated by an insulating material, or dielectric. Its primary function is to store electrical energy.
A capacitor is a passive electrical component that can store energy in the electric field between a pair of conductors (called “plates”). In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action.
A capacitor is an electrical component used to store energy in an electric field. It has two electrical conductors separated by a dielectric material that both accumulate charge when connected to a power source.
