A Capacitor is a passive electronic component or device capable of storing charge with a certain voltage level across two conducting plates or surfaces, separated by an insulating material or dielectric substance. There are three fundamental electronic components that form the foundation of a circuit – resistors, inductors, and capacitors. A capacitor in an electrical circuit behaves as a charge storage device. It holds the electric charge when we apply a voltage across it, and it gives up the stored charge to the circuit as when required. The most basic construction of a capacitor consists of two parallel conductors (usually metallic plates) separated by a dielectric material. When we connect a voltage source across the capacitor, the conductor (capacitor plate) attached to the positive terminal of the source becomes positively charged, and the conductor (capacitor plate) connected to the negative terminal of the source becomes negatively charged. Because of the presence of dielectric in between the conductors, ideally, no charge can migrate from one plate to other.
