During charging a capacitor variation of potential V of the capacitor with time t is shown as                           [MP PET 2003]

A)                            

B)           

C)                     

D)  

Correct Answer: A

Solution :

              For charging of capacitor \[q={{q}_{0}}\left( 1-{{e}^{-\,\frac{t}{CR}}} \right)\] and potential difference \[V={{V}_{0}}\left( 1-{{e}^{-\,\frac{t}{CR}}} \right)\]
