Capacitor
A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, the capacitor stores energy in the form of an electric field.
What is a Capacitor?
Capacitors are widely used in electronic circuits for various purposes such as filtering, smoothing, timing, tuning, and coupling. They come in different types and sizes, ranging from small surface-mount capacitors used in consumer electronics to large electrolytic capacitors used in power supplies.
