    In the figure, the equivalence capacitance between A and B is

    A)  3.75\[\mu F\]

    B)  5.25\[\mu F\]

    C)  6.5\[\mu F\]                     

    D)  10.5\[\mu F\]

    Correct Answer: A

    Solution :

                    It is a balance Wheatstone bridge \[{{C}_{AB}}=\frac{5\times 3}{5+3}+\frac{5\times 3}{5+3}\] \[{{C}_{AB}}=2\times \frac{15}{8}=\frac{15}{4}=3.75\,\mu F\]
