6 FAQs about [Why does the inductor store energy ]
How do inductors store energy?
Inductors store energy in their magnetic field when current flows through them. This energy storage depends on the inductor’s inductance and current. An inductor is a passive electronic component that plays a crucial role in various electronic circuits by storing energy in its magnetic field when an electric current flows through it.

As the current flows through the inductor, the magnetic field builds up and stores energy. The energy stored in the inductor is proportional to the square of the current and the inductor’s inductance. When the current decreases or stops, the magnetic field collapses, and the stored energy is released back into the circuit.
