    If there are n capacitors in parallel connected to V volt source, then the energy stored is equal to             [AIEEE 2002]

    A)            CV 

    B)            \[\frac{1}{2}nC{{V}^{2}}\]

    C)            \[C{{V}^{2}}\]                      

    D)            \[\frac{1}{2n}C{{V}^{2}}\]

    Correct Answer: B

    Solution :

               \[U=\frac{1}{2}{{C}_{eq}}{{V}^{2}}=\frac{1}{2}(nC){{V}^{2}}\]
