The mutual inductance of two coils C_1 and C_2 is 20 mH. In coil C_1, the current changes from 4 A to zero in 0 · 2 s. If the resistance of coil C_2…

The mutual inductance of two coils $\displaystyle \mathrm{C}_{1}$ and $\displaystyle \mathrm{C}_{2}$ is $\displaystyle 20$ mH . In coil $\displaystyle \mathrm{C}_{1}$, the current changes from $\displaystyle 4$ A to zero in $\displaystyle 0 \cdot 2 \mathrm{~s}$. If the resistance of coil $\displaystyle \mathrm{C}_{2}$ is $\displaystyle 4 \Omega$, then the charge that flows through it per second will be :
