  • question_answer
       A, B and C are the three coils of conductor having different number of turns, wound around a soft iron ring as shown in the figure. Ends of coils B and C are connected to the galvanometers. The observation that can be made when ends of coil A are connected to an A.C. source is:

    A) Same electric current is induced in B and C              

    B) No electric current is induced in B and C                

    C) Induced electric current is more in B than in C           

    D) induced electric current is less in B than in C            

    Correct Answer: C

    Solution :

    (c) induced electric current is more in B than in C When the end of coil A is connected to an A.C. source the induced electric current wilt be more in B than in C as the number of turns in the coil is more in B than in C.
