JEE Main & Advanced Physics Electrostatics & Capacitance Question Bank Grouping of Capacitors

  • question_answer
    Three identical capacitors are combined differently. For the same voltage to each combination, the one that stores the greatest energy is                                             [MP PMT 1995]

    A)                    Two in parallel and the third in series with it

    B)                    Three in series

    C)                    Three in parallel

    D)                    Two in series and third in parallel with it

    Correct Answer: C

    Solution :

                       \[U=\frac{1}{2}C{{V}^{2}}\] Now if V is constant, then U is greatest when \['{{C}_{eq}}'\] is maximum. This is when all the three are in parallel.
