Question

The figure shows a part of a complete circuit. The potential difference $V_B-V_A$ when the current $I$ is 5 A and is decreasing at a rate of $10^3 \mathrm{As}^{-1}$ is given by

Professor PC Thomas Classes · Answer

Apply Kirchhoff's voltage law across the inductor and resistor taking into account $L(di/dt)$ and $iR$ drops to find $V_B - V_A$.
