A capacitor is a fundamental component in electrical and electronic circuits, primarily designed to store and release electrical energy. It consists of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric field forms, allowing the capacitor to store energy in the form of an electrostatic field.
Capacitors can help regulate voltage levels in electronic circuits. They can absorb excess voltage spikes or surges, protecting sensitive components from damage.
