Vedclass · Answer

(B) When an insulator (dielectric) plate enters the capacitor,the capacitance $C$ increases because $C = \frac{K \epsilon_0 A}{d}$.Since the capacitor is connected to a battery,the potential difference $V$ remains constant.The charge on the capacitor $Q = CV$ increases as the plate enters.This increase in charge requires a current to flow from the battery to the capacitor plates,which corresponds to a charging current in the external circuit.Inside the capacitor,the displacement current $I_d$ is equal to the conduction current in the external circuit,so it flows in the direction that supports the charging process (clockwise).As the insulator plate leaves the capacitor,the capacitance $C$ decreases,causing the charge $Q$ on the capacitor to decrease.This results in a discharge current flowing out of the capacitor,meaning the displacement current now flows in the opposite direction (anticlockwise).Therefore,the displacement current first flows clockwise and then anticlockwise.
