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:

A $there is no current.$
B $displacement current of magnitude equal to I flows in the same direction as I .$
C $displacement current of magnitude equal to I flows in a direction opposite to that of I .$
D $displacement current of magnitude greater than I flows but can be in any direction.$

Solution & Step-by-step Explanation

According to the Ampere-Maxwell law, the conduction current I_{c} in the wires is equal to the displacement current I_{d} in the gap between the capacitor plates to maintain continuity of current. I_{d} = ϵ_{0} \frac{d Φ _{E}}{d t} In magnitude, I_{d} = I, and it acts in the same direction to complete the circuit.

Try it yourself before checking the explanation above.

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:

there is no current.

displacement current of magnitude equal to I flows in the same direction as I .

displacement current of magnitude equal to I flows in a direction opposite to that of I .

displacement current of magnitude greater than I flows but can be in any direction.
