  • question_answer
    Directions: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as: Assertion (A): If we bend an insulated conducting wire, the resistance of the wire increases. Reason (R): The drift velocity of electrons in bent wire decreases.                                             

    A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)        

    B) Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)

    C) Assertion (A) is true but Reason (R) is false             

    D) Assertion (A) is false and Reason (R) is also false

    Correct Answer: D

    Solution :

    (d) Bending will not increase the resistance of the conducting wire. Also drift velocity of electron is independent of bending of conductor.
