STANDARD Physics Displacement Current MCQ Question
Type: MCQ-numerical-Medium-Class 12
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
A
zero, zero
B
zero, 60 μA
C
60 μA, 60 μA
D
60 μA, zero
Correct Answer
Option C
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.
