6 FAQs about [Capacitor and inductor energy storage example]

Are inductor and capacitor a passive device?

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 is the difference between a capacitor and an inductor?

The energy of a capacitor is stored within the electric field between two conducting plates while the energy of an inductor is stored within the magnetic field of a conducting coil. Both elements can be charged (i.e., the stored energy is increased) or discharged (i.e., the stored energy is decreased).

How to calculate the energy stored in a capacitor or inductor?

The energy stored in the state of a capacitor or inductor should be calculable by integrating the power absorbed by the device. Suppose we want to know the energy stored in an inductor in a given state.
