$A$ coil with resistance $20\, \Omega$ and inductance $5\, H$ is connected to a $100\, V$ battery. The energy stored in the coil will be .... $J$.

Which of the following statements are correct?
$(a)$ An inductor stores energy in the form of a magnetic field.
$(b)$ $A$ capacitor stores energy in the form of an electric field.
$(c)$ An inductor stores energy in the form of both electric and magnetic fields.
$(d)$ $A$ capacitor stores energy in the form of both electric and magnetic fields.

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

The magnetic potential energy stored in a certain inductor is $25\, mJ,$ when the current in the inductor is $60\, mA.$ This inductor is of inductance ......$H$.

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

$A$ coil of self-inductance $0.5 \ mH$ carries a current of $2 \ A$. The energy stored in Joule is . . . . . . .
