  • question_answer
    A transformer connected to 220 volt line shows an output of 2 A at 11000 volt. The efficiency is 100%. The current drawn from the line is                                             [MP PMT 1995]

    A)            100 A                                       

    B)            200 A

    C)            22 A                                         

    D)            11 A

    Correct Answer: A

    Solution :

               \[\frac{{{V}_{s}}}{{{V}_{p}}}=\frac{{{i}_{p}}}{{{i}_{s}}}\Rightarrow {{i}_{p}}=\frac{11000\times 2}{220}=100\ A\]
