    Heat produced in a wire of resistance R due to current flowing at constant potential difference, is proportional to :

    A)  \[\frac{1}{{{R}^{2}}}\]                                  

    B)         \[\frac{1}{R}\]                 

    C)         \[R\]                                    

    D)         \[{{R}^{2}}\]

    Correct Answer: B

    Solution :

    Heat produced at constant potential difference\[=\frac{{{V}^{2}}}{R}\] So,          \[H\propto \frac{1}{R}\]
