    Question

    When electric current is passed through a wire, the

    amount of heat produced in a wire depends upon _____. I. Length II. Thickness
    A Only II Correct Answer Incorrect Answer
    B Both I and II Correct Answer Incorrect Answer
    C Only I Correct Answer Incorrect Answer
    D Neither I nor II Correct Answer Incorrect Answer

    Solution

    The heat generated in the conductor depends upon its resistance. The resistance of the wire further depends upon the length and thickness of the wire. So both the length and thickness of the wire will affect the amount of heat.
