  • question_answer A cable of resistance \[10\,\Omega \] carries electric power from a generator producing 250 kW at 10000 volt. The current in the cable is

    A)            25 A                                         

    B)            250 A

    C)            100 A                                       

    D)            1000 A

    Correct Answer: A

    Solution :

               Since \[P=VI\,\]Þ \[I=\frac{P}{V}=\frac{250000}{10000}=25\,\,A\]
