A parallel plate capacitor of capacitance $20\mathrm{\mu F}$ 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

  $\text{ zero, zero }$

• B

  $\text{ zero, }60\mathrm{\mu A}$

• C

  $60\mathrm{\mu A},60\mathrm{\mu A}$

• D

  $60\mathrm{\mu A}, \mathrm{zero}$
