Q.

A parallel plate capacitor is charged by connecting it to a battery through a resistor. If I is the current in the circuit, then in the gap between the plates          [2024]

1 there is no current.  
2 displacement current of magnitude equal to I flows in the same direction as I.  
3 displacement current of magnitude equal to I flows in a direction opposite to that of I.  
4 displacement current of magnitude greater than I flows but can be in any direction.  

Ans.

(2)

Displacement current is equal to the conduction current and flows from positive plate towards negative plate in the direction of conduction current.
