    A thermo couple develops \[200\,\mu \,V\] between \[{{0}^{o}}C\] and \[{{100}^{o}}C.\] If it develops \[64\,\,\mu \,V\] and \[76\,\mu \,V\] respectively between \[({{0}^{o}}C-{{32}^{o}}C)\] and \[({{32}^{o}}C-{{70}^{o}}C)\]then what will be the thermo emf it develops between \[{{70}^{o}}C\] and \[{{100}^{o}}C\]

    A)            \[65\,\,\mu \,V\]               

    B)            \[60\,\,\mu V\]

    C)            \[55\,\,\mu V\]                   

    D)            \[50\,\,\mu V\]

    Correct Answer: B

    Solution :

                       By using \[e_{0}^{100}=e_{0}^{32}+e_{32}^{70}+e_{70}^{100}\] Þ \[200=64+76+e_{70}^{100}\]Þ \[e_{70}^{100}=60\,\mu V\]
