JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Application of EMI (Motor, Dynamo, Transformer)

  • question_answer
    The turn ratio of a transformers is given as 2 : 3. If the current through the primary coil is 3 A, thus calculate the current through load resistance                      [BHU 2005]

    A)            1 A

    B)            4.5 A

    C)            2 A

    D)            1. 5 A

    Correct Answer: C

    Solution :

               As \[\frac{{{I}_{P}}}{{{I}_{s}}}=\frac{{{n}_{p}}}{{{n}_{s}}}\]; i.e. \[\frac{3}{{{I}_{s}}}=\frac{3}{2}\Rightarrow {{I}_{s}}=2A\].
