Question:

Instantaneous displacement current 1A in the space between the parallel plates of 1µF capacitor can be established by changing the potential difference at the rate of:

Options:

0.1 V/s

1 V/s

106 V/s

10-6 V/s

Correct Answer:

106 V/s

Explanation:

$I_{D}=\frac{dq}{dt}=C \frac{dv}{dt}$ or $\frac{dv}{dt}=\frac{I_{D}}{C}=\frac{1}{10^{-6}}$ = 106 V/s
