  • question_answer
    One microfarad capacitor is joined to a 200V, 50Hz alternator. The rms current through capacitor is:

    A) \[6.28\times {{10}^{-2}}A\]

    B) \[7.5\times {{10}^{-4}}A\]              

    C) \[10.52\times {{10}^{-2}}A\]        

    D) \[15.25\times {{10}^{-2}}A\]

    Correct Answer: A

    Solution :

    (a) \[6.28\times {{10}^{-2}}A\]             Current, \[{{l}_{v}}=2\times 3.14\times 50\times {{10}^{-6}}\times 200=6.28\times {{10}^{-2}}A\]
