Instantaneous displacement current 1A in the space between the parallel plates of 1$\mu$ F capacitor can be established by changing the potential difference at the rate of:
Answer & explanation
Correct answer: option 3
$I_d = \frac{dq}{dt} = C\frac{dV}{dt}$
$\Rightarrow \frac{dV}{dt} = \frac{I_d}{C} = \frac{1}{10^{-6}} = 10^6 V/s$
