Question:

Instantaneous displacement current of 1.0 A in the space between the parallel plate of 1 μF capacitor can be established by changing potential difference of

Options:

10−6Vs−1

106Vs−1

1 Vs−1

0.1 Vs−1

Correct Answer:

106Vs−1

Explanation:

$\frac{Q}{t}=\frac{CV}{t} or i_d = C(\frac{V}{t})$

 $\Rightarrow \frac{V}{t}=\frac{i_d}{C}=\frac{1.0}{10^{-6}}Vs^{-1} = 10^6 Vs^{-1}$
