Inductors and capacitors are energy storage devices, which means energy can be stored in them. But they cannot generate energy, so these are passive devices. The inductor stores energy in its magnetic field; the capacitor stores energy in its electric field.

What are inductors and capacitors used for?

Capacitors and inductors are electronic components that can store energy supplied by a voltage source. A capacitor stores energy in an electric field; an inductor stores energy in a magnetic field.

What is difference between capacitor and inductor?

One of the main differences between a capacitor and an inductor is that a capacitor opposes a change in voltage while an inductor opposes a change in the current. Furthermore, the inductor stores energy in the form of a magnetic field, and the capacitor stores energy in the form of an electric field.
