STANDARD Physics Displacement Current MCQ Question
A parallel plate capacitor of capacitance 20 μF is being charged by a voltage source whose potential is changing at the rate of 3 V/s. The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively
zero, zero
zero, 60 μA
60 μA, 60 μA
60 μA, zero
Correct Answer
Detailed Explanation
The displacement current is equal to the conduction current. Given C = 20 μF and dV/dt = 3 V/s, the current is I = C * dV/dt = 20 μF * 3 V/s = 60 μA.
