  • question_answer 39) In the circuit shown in the figure. The effective capacitance between A and B is:

    A) \[3\,\mu F\]                 

    B) \[2\,\mu F\] 

    C) \[4\,\mu F\]                 

    D) \[8\,\mu F\] 

    Correct Answer: C

    Solution :

    Hence, the figure. \[2\mu F\]and \[2\mu F\]capacitors are in parallel. \[{{C}_{p}}=2+2=4\mu F.\] Now the two pairs of \[4\mu F\]capacitors are in series. \[\therefore \]\[{{C}_{{{s}_{1}}}}=2\mu F;\] \[{{C}_{{{s}_{2}}}}=2\mu F\] Across A, B the two pairs are in parallel. \[\therefore \]\[{{C}_{p}}=2+2=4\mu F.\] Hence, the correction option is [c].
