| A: The neutral temperature does not depend on temperature of cold junction. |
| B: The inversion temperature does not depend on temperature of cold junction. |
A) both A and B are correct
B) A is correct but B is wrong
C) A is wrong but B is correct
D) both A and B are wrong
Correct Answer: B
Solution :
The temperature \[{{T}_{n}}\]of hot junction at which thermo emf becomes maximum is called neutral temperature, it can also be defined as the temperature of hot junction at which maximum current flows in thermo couple. It is independent of the temperature of cold junction. It depends upon nature of metals. The temperature\[{{T}_{1}}\]for which thermo emf becomes zero and changes direction is called temperature of inversion, it depends upon the temperature of cold junction. Therefore, statement A is correct and B is wrong.
