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 a Capacitor: Storing Energy in Electrical Fields

When devices don''t need power, capacitors store energy like a tiny power store. When devices need this energy, the magic happens. The discharging capacitor stage starts, and the stored energy is used. It powers up different electronic parts. Capacitors can move between storing and releasing energy well. This stops energy from being wasted.
