A parallel plate capacitor 20 `muF` 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, `60 muA`
C. `60 muA, 60muA`
D. `60 muA`, zero

Answer

C

Explanation

`Q=CV`
`(dQ)/(dt)=i=C(dv)/(dt)`
`=20 muFxx(3V)/(s)`
`=60 muA`
For circuit to be completed displacement current should be equal to conduction current.
