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

Text Solution
Verified by ExpertsThe correct answer is:
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 decreases, hence current in outer circuit flows form B to A and then form A to B.
