If\[{{\theta }_{i}}\]is the inversion temperature,\[{{\theta }_{n}}\]is the neutral temperature, \[{{\theta }_{c}}\]is the temperature of the cold junction for thermocouple, then

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

B)                         \[{{\theta }_{i}}-{{\theta }_{c}}=2{{\theta }_{n}}\]

C)  \[\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\theta n\]       

D)         \[{{\theta }_{c}}-{{\theta }_{i}}=2{{\theta }_{n}}\]

Correct Answer: C

Solution :

                \[{{\theta }_{n}}-{{\theta }_{c}}={{\theta }_{i}}-{{\theta }_{n}}\] or            \[{{\theta }_{n}}=\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\]
