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 :
Answer: (D) displacement current of magnitude equal to I flows in the same direction as I.
The conduction current $I$ in the wires continues across the gap as displacement current $I_d = \epsilon_0\dfrac{d\phi_E}{dt}$.
The total current (conduction + displacement) is continuous, so $I_d = I$. It flows in the same direction as $I$: the field between the plates grows in the direction of the current.
