  • question_answer
    Two capacitors \[{{C}_{1}}\] and \[{{C}_{2}}\] are charged to 120 V and 200 V respectively. It is found that by connecting them together the potential on each one can be made zero. Then

    A) \[3{{C}_{1}}\,=\,5{{C}_{2}}\]

    B) \[3{{C}_{1}}\,+\,5{{C}_{2}}=0\]

    C) \[9{{C}_{1}}\,=\,4{{C}_{2}}\]

    D) \[5{{C}_{1}}\,=\,3{{C}_{2}}\]

    Correct Answer: A

    Solution :

    [a] \[120{{C}_{1}}=200{{C}_{2}}\] \[6{{C}_{1}}=10{{C}_{2}}\] \[3{{C}_{1}}=5{{C}_{2}}\]
