A power capacitor is a device used to store electric energy in an electric field or electrostatic field. It is similar to a battery but works on the principle of capacitance. It has two conducting plates which are separated by a dielectric. The dielectric can be either solid, liquid or gas material.
A capacitor utilizes an electric field to store its potential energy, while a battery stores its energy in chemical form. Battery technology offers higher energy densities, allowing them to store more energy per unit weight than capacitors. However, batteries may discharge more slowly due to chemical reaction latencies.
