Q. During charging a capacitor variation of potential $V$ of the capacitor with time $t$ is shown as
A) [image:1_image149.emf]
B) [image:1_image150.emf]
C) [image:1_image151.emf]
D) [image:1_image152.emf]
Explanation
(a) For charging of capacitor $q = q_{0}\left( 1 - e^{\frac{t}{CR}} \right)$ and potential difference $V = V_{0}\left( 1 - e^{- \frac{t}{CR}} \right)$
