Vedclass · Answer

(B) According to Kirchhoff's voltage law $(KVL)$,the algebraic sum of potential differences around any closed loop is zero.For an inductive circuit with no resistance,the potential difference across the source $V$ and the induced electromotive force $(EMF)$ across the inductor $L$ must balance each other.The induced $EMF$ across an inductor is given by $\varepsilon = -L \frac{di}{dt}$.Applying $KVL$ to the loop:$V + \varepsilon = 0$$V + (-L \frac{di}{dt}) = 0$$V - L \frac{di}{dt} = 0$$V = L \frac{di}{dt}$

There is no resistance in the inductive circuit. Kirchhoff's voltage law for the circuit is
