A capacitor is a passive electronic component that stores electrical energy in an electric field. It is a two-terminal component with a capacitance measured in farads (F). Capacitors are used in electronic circuits to store energy, filter out noise, and smooth out voltage fluctuations.
Capacitors are made from two conductive plates separated by an insulating material. When a voltage is applied to the plates, an electric field is created between them. This electric field stores the electrical energy. The capacitance of a capacitor is determined by the size of the plates, the distance between them, and the type of insulating material used.
