Q. 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, 60 μA
B) 60 μA, 60 μA
C) 60 μA, zero
D) zero, zero
Explanation

[Solution] $I = C\frac{dV}{dt} = 20 \times 10^{-6} \times 3 = 60$ μA; conduction and displacement currents are equal. Answer (2).
