The average emf induced in the coil, in $mV$ is, when a coil has $1000$ turns and $500{ \mathrm{cm}}^2$ as its area. The plane of the coil is placed at right angles to a magnetic induction field of $2\times {10}^{-5} {\mathrm{Wbm}}^{-2}$. The coil is rotated through $180°$ in $0.2 \mathrm{s}$.

Two different coils have self inductance $L_1=8 \mathrm{mH}$ and $L_2=2 \mathrm{mH}$, respectively. The current in one coil is increased at a constant rate and the current in the second coil is also increased at the same constant rate. At a certain instant of time, the power given to the two coils is same. At that time, the current, the induced voltage and the energy stored in the first coil are $i_1, V_1$ and $W_1$, respectively. The corresponding values for the second coil, at the same instant, are $i_2, V_2$ and $W_2$, respectively. Now, select the incorrect option.
