Capacitors and inductors possess the following three special properties that make them very useful in electric circuits: (a) The capacity to store energy makes them useful as temporary voltage or current sources. Thus, they can be used for generating a large amount of current or voltage for a short period of time.
The energy stored in a capacitor is the integral of the instantaneous power. Assuming that the capacitor had no charge across its plates at tv =−∞ [ ()−∞ =0 ] then the energy stored
As mentioned before, the energy-storage properties of capacitors and inductors do interesting things to the time-based behavior of circuits.

Inductors have the exact opposite characteristics of capacitors.

Inductors and Inductance. A major difference between a capacitor and an inductor is that a capacitor stores energy in an electric field while the inductor stores energy in a magnetic field.
