The magnetic energy stored in an inductor of inductance $5 \mu H$ carrying a current of $2 \ A$ is

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

Energy stored in a coil of self-inductance $40 \, mH$ carrying a steady current of $2 \, A$ is.....$J$

The energy stored in a coil of inductance $L$ carrying a steady current $i$ is in the form:

The energy stored in a $50 mH$ inductor carrying a current of $4 A$ is (in $J$)

The magnetic potential energy stored in a certain inductor is $25 \ mJ$,when the current in the inductor is $50 \ mA$. What is the inductance (in $H$)?
