    If the cold junction of a thermo-couple is kept at \[{{0}^{o}}C\]and the hot junction is kept at \[{{T}^{o}}C,\] then the relation between neutral temperature \[({{T}_{n}})\] and temperature of inversion \[({{T}_{i}})\] is :-

    A)  \[{{T}_{n}}={{T}_{i}}+T\]                             

    B)  \[{{T}_{n}}={{T}_{i}}/2\]

    C)  \[{{T}_{n}}=2{{T}_{i}}\]                

    D)  \[{{T}_{n}}={{T}_{i}}-T\]

    Correct Answer: B

    Solution :

    \[\because \]  \[{{T}_{n}}=\frac{{{T}_{C}}+{{T}_{i}}}{2}\] & \[{{T}_{C}}={{0}^{o}}C\] \[\therefore \]\[{{T}_{n}}=\frac{{{T}_{i}}}{2}\]
