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

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

Energy in a current carrying coil is stored in the form of

$A$ coil has an inductance of $2 \, H$ and resistance of $4 \, \Omega$. $A$ $10 \, V$ potential difference is applied across the coil. The energy stored in the magnetic field after the current has built up to its equilibrium value will be $.......... \times 10^{-2} \, J$.

If the current flowing through a coil is reduced by $50 \%$,then the energy stored in the coil will

If a current of $4 \ A$ produces a magnetic flux of $3 \times 10^{-3} \ Wb$ through a coil of $400$ turns,the energy stored in the coil will be: (in $J$)
