A) 4:1
B) 2:1
C) 1:2
D) 1 :1
Correct Answer: B
Solution :
Work done by battery is given by \[W=qV=(CV)\,V=C{{V}^{2}}\,\,\,\,(\because \,\,q=CV)\] ...(1) Now, energy stored by capacitor is given by \[U=\frac{1}{2}C{{V}^{2}}\] ?...(2) From equations (1) and (2), we obtained \[\frac{W}{U}=\frac{2}{1}=2:1\]You need to login to perform this action.
