A capacitor has been charged by a DC source. What are the magnitude of conduction and displacement current when it is fully charged?

A

`I_(d) = I_(c) = 1`

B

`I_(d) = I_(c) = 0`

C

`I_(d) = 1, I_(c) = 0`

D

`I_(d) = 0, I_(c) = 1`

Text Solution

Verified by Experts

The correct Answer is:
B
Displacement current, `I_(d) = epsi_(0)(dphi)/(dt) = epsi_(0)(d(q//epsi_(0)))/(dt) = 0`
Conduction current, `I_(c) = c(dv)/(dt) = 0` [as voltage becomes constant when the capacitor became fully charged]
