Energy Storage Elements: Capacitors and Inductors

Capacitors and inductors, which are the electric and magnetic duals of each other, differ from resistors in several significant ways. • Unlike resistors, which dissipate energy, capacitors and inductors do not dissipate but store energy, which can be retrieved at a later time. They are called storage elements.
