    Thomson coefficient of a conductor is \[10\mu V/K\]. The two ends of it are kept at \[{{50}^{o}}C\] and \[{{60}^{o}}C\]  respectively. Amount of heat absorbed by the conductor when a charge of 10C flows through it is                                              [EAMCET 2001]

    A)            1000 J                                      

    B)            100 J

    C)            100 mJ                                    

    D)            1 mJ

    Correct Answer: D

    Solution :

                       By using \[H=\sigma Q\theta \]            Þ  \[H=(10\times {{10}^{-6}})\times 10\times (60-50)={{10}^{-3}}J=1\,\,mJ\]
