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:

A

zero, zero

B

zero, `60muA`

C

`60muA, 60muA`

D

`60muA`, zero

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `C=20muF`
The rate og change of potential = 3 V/s
The charge on the capacitor, `Q=CV`
`therefore" "(dQ)/(dt)=I_(D)=C(dV)/(dt)=20muFxx(2V)/(s)=60muA`
Displacement current is equal to the conduction current.
