  • question_answer
    For a metallic wire, the ratio \[V/i\] \[(V=\] the applied potential difference, i = current flowing) is           [MP PMT 1994; BVP 2003]

    A)                    Independent of temperature

    B)                    Increases as the temperature rises

    C)                    Decreases as the temperature rises

    D)                    Increases or decreases as temperature rises, depending upon the metal

    Correct Answer: B

    Solution :

                 As \[\frac{V}{i}=R\]and \[R\propto \] temperature
