JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Faraday's and Lenz's Law

  • question_answer
    In electromagnetic induction, the induced charge in a coil is independent of

    A)            Change in the flux             

    B)            Time

    C)            Resistance in the circuit   

    D)            None of the above

    Correct Answer: B

    Solution :

                       We know that \[e=\frac{d\varphi }{dt}\]            But e=iR and \[i=\frac{dq}{dt}\Rightarrow \frac{dq}{dt}R=\frac{d\varphi }{dt}\]  Þ\[\ dq=\frac{d\varphi }{R}\]
