  • question_answer
    The cold junction of a thermocouple is maintained at \[10{}^\circ C\]. No thermo e.m.f. is developed when the hot junction is maintained at \[530{}^\circ C\]. The neutral temperature is [MP PMT 1994]

    A)            \[260{}^\circ C\]                 

    B)            \[270{}^\circ C\]

    C)            \[265{}^\circ C\]                 

    D)            \[520{}^\circ C\]

    Correct Answer: B

    Solution :

               \[{{T}_{n}}=\frac{{{T}_{i}}+{{T}_{c}}}{2}=\frac{10+530}{2}={{270}^{o}}C\]
