Capacitors 101: What Do Capacitors Store in Electronic Circuits?
Published By. A capacitor is a two-terminal electrical component used to store energy in an electric field. Capacitors contain two or more conductors, or metal plates, separated by an insulating layer referred to as a dielectric. The conductors can take the form of thin films, foils or beads of metal or conductive electrolyte, etc.
