A parallel plate capacitor of capacitance $$20 \mu F$$ 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

$$60 \mu A, 60 \mu A,$$

B

$$60 \mu A, zero$$

C

$$zero, zero$$

D

$$zero, 60 \mu A,$$
