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:

Options

A. Zero, zero
B. Zero, `60mu A`
C. `60 muA, 60muA`
D. `60 muA`, zero

Answer

C

Explanation

Q = CV
`(dQ)/(dt)=i=C(dV)/(dt)=20muF xx(3V)/s = 69muA`
For circuit to be completed displacement current should be equal to conduction current.
