Inductor-Stored Energy
Inductor-stored energy is the energy stored in an inductor, a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current is flowing through it.
The inductor-stored energy equals half the magnetic inductance times the electric current squared.
Formula
