Capacitors in DC Circuits & RC

A parallel plate capacitor of capacitance 20 $\mu$ F is being charged by a voltage source whose potential is changing at the rate of 3V/s. The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively:

Show answer and solution

Answer: (c)

Conduction current in the wires $I = C\dfrac{dV}{dt} = (20\times10^{-6})(3) = 60\ \mu\text{A}$ .
Displacement current between the plates always equals the conduction current in the wires.
So the answer is (c) $60\ \mu\text{A}$ , $60\ \mu\text{A}$ .
