What electrical component stores energy in an electric field?

A capacitor is constructed from two conductive plates separated by an insulating material known as a dielectric. When voltage is applied across the plates, electrostatic charge builds up, allowing the capacitor to store energy temporarily in an electric field. It is crucial to distinguish between capacitors and inductors. While capacitors store energy in an electric field, inductors store energy in a magnetic field. Resistors do not store energy at all (they dissipate it as heat), and diodes simply allow current to flow in only one direction.
