The capacity of a parallel plate air capacitor is `2 mu F` and voltage beteen the plates is changing at the rate of 3 v/s the displacement current in the capacitor is

Options

A. 2 unit
B. 3 unit
C. 5 unit
D. 6 unit

Answer

D

Explanation

`V=Q/C`
`(dV)/(dt) = 1/C (dQ)/(dt) =1/C xxi " " [(dQ)/(dt) =i]`

`(dV)/(dt)=i/Cimplies i=Cxx(dV)/(dt)=2xx3=6` unit.
