Physics - EMI/AC Question with Solution | TestHub

$\mathrm{I}=-\frac{\mathrm{I}}{{\mathrm{R}}^{\prime }}\frac{\mathrm{d}\varphi }{\mathrm{dt}}$ or, I $=-\frac{1}{R^{\prime }}\mathrm{n}\left[\frac{{\mathrm{W}}_2-{\mathrm{W}}_1}{{\mathrm{t}}_2-{\mathrm{t}}_1}\right]$ ( $W_1$ and $W_2$ are not the magnetic field, but the values of flux associated with one turn of coil) $I=\frac{-1}{(R+4R)}\frac{n\left(W_2-W_1\right)}{t}$ or, $\mathrm{I}=-\frac{\mathrm{n}\left({\mathrm{W}}_2-{\mathrm{W}}_1\right)}{5\mathrm{Rt}}$
