JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Assertion and Reason

  • question_answer
    Assertion             :       Inductance coil are made of copper. Reason                 :   Induced current is more in wire having less resistance.

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: A

    Solution :

                The inductance coils made of copper will have very small ohmic resistance. Due to change in magnetic flux a large induced current will be produced in such an inductance, which will offer appreciable opposition to the flow of current.
