Question

An insulator plate is passed between the plates of a capacitor. Then current (A) first flows from A to Band then from B to A (B) first flows from B to A and then from A to B (C) always flows from B to A (D) always flows from A to B

As insulator plate is passed between the plates of the capacitor, its capacity increases first and then decreases as the plate slips out. As a result, positive charge on plate A increases first and then decrease, hence, current in outer circuit flows from B to A and then from A to B.

Q. An insulator plate is passed between the plates of a capacitor. Then current

first flows from A to Band then from B to A

first flows from B to A and then from A to B

always flows from B to A

always flows from A to B

As insulator plate is passed between the plates of the capacitor, its capacity increases first and then decreases as the plate slips out. As a result, positive charge on plate $A$ increases first and then decrease, hence, current in outer circuit flows from $B$ to $A$ and then from $A$ to $B$ .
