$A$ $100\, mH$ coil carries a current of $1\, A$. The energy stored in its magnetic field is......$J$.

The energy stored in an inductor of self-inductance $L$ henry carrying a current of $I$ ampere is:

In an inductor of inductance $L = 100 \, mH$,a current of $I = 10 \, A$ is flowing. The energy stored in the inductor is ....... $J$.

Define an inductor. Derive the equation for the energy $U = \frac{1}{2}LI^2$ stored in an inductor.

When a current $I$ flows through a coil,it stores the energy $E_1$ in it. Now the current is reduced to $I/2$,the energy stored in the coil becomes $E_2$. The change in the energy is

$A$ $50 \, mH$ coil carries a current of $2 \, A$. The energy stored in the coil in joules is:
