Introduction to Capacitor Technologies

When AC voltage is applied to a capacitor, current starts to flow through its dielectric material and all of its conductive parts such as electrodes and lead wires/terminations. In a practical capacitor, some part of the current passing through the capacitor is dissipated because there is a small amount of resistance to the flow of current.

Capacitor in Electronics

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.
