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.

What is the difference between a battery and a capacitor?

Compared to batteries, capacitors have a lower energy density, storing less energy per unit of volume or mass. This makes them less suitable for long-duration energy storage. Another key difference is the self-discharge property: capacitors tend to lose their stored energy relatively quickly when not in use.
