At what rate the potential difference between the plates of a parallel plate capacitance `2 mu F` should be changed to establish a displacement current of 2mA between its plates?

Options

A. `2 xx 10^(2) V//s`
B. `2 xx 10^(3) V//s`
C. `10^(3) V//s`
D. `2 xx 10^(-3) V//s`

Answer

C

Explanation

`I_(D) = C(dV)/(dt) :. (I_D)/C = (2 xx 10^(-3))/(2 xx 10^(-6))`
`:. (dV)/(dt) = 10^(3) V//s`.
