Capacitors

A capacitor is a device that stores electrical energy temporarily, similar to a rechargeable battery. It consists of two conductive plates separated by an insulating material called a dielectric. When connected to a power source, the capacitor accumulates charge on its plates. Once charged, it can release that stored energy when needed, providing a quick burst of power or smoothing out electrical signals. Capacitance measures how much charge the capacitor can hold, and they are essential in various electronic applications, such as filtering signals, tuning circuits, and energy storage.
