  • question_answer
    Two capacitors of capacity \[{{C}_{1}}\] and \[{{C}_{2}}\] are charged upto a potential \[{{V}_{1}}\] and \[{{V}_{2}}\], then condition for not flowing the charge between on connected them in parallel:

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

    B)         \[{{C}_{1}}{{V}_{1}}={{C}_{2}}{{V}_{2}}\]

    C)  \[{{V}_{1}}={{V}_{2}}\]                

    D)         \[\frac{{{C}_{1}}}{{{V}_{1}}}=\frac{{{C}_{2}}}{{{V}_{2}}}\]

    Correct Answer: B

    Solution :

    If charge on both the capacitor is same then transfer of energy does not take place.                                 \[q=CV\] \[\therefore \]  \[{{C}_{1}}{{V}_{1}}={{C}_{2}}{{V}_{2}}\] is the required condition.
