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.
(1) Zero, 60 $\mu$A
(2) 60 $\mu$A, 60 $\mu$A
(3) 60 $\mu$A, zero
(4) Zero, zero
(1) Zero, 60 $\mu$A
(2) 60 $\mu$A, 60 $\mu$A
(3) 60 $\mu$A, zero
(4) Zero, zero
