Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When a decreasing current flows from point A to point B through an ideal inductor, the electric potential at point A is lower than the electric potential at point B ( V_A Reason (R): According to Lenz's law, the induced emf opposes the decrease in current, making the inductor act as a source with i

Step-by-step solution

When current flows from A to B, the potential difference equation is V_A - L di dt = V_B . Since the current is decreasing, di dt is negative. Therefore, the term -L di dt becomes positive, which means V_A + positive value = V_B . This implies V_A According to Lenz's law, the induced emf opposes the change in current. To oppose a decrease, the inductor attempts to maintain the current flow in the same direction (from A to B). To drive current from A to B, it must act like a battery with its positive terminal at B a
