Q. For a given thermocouple neutral temperature
A) Is a constant
B) Depends on cold junction temperature
C) Depends on inversion temperature
D) Double that of cold junction temperature
Explanation
(a) Neutral temperature is defined as temperature of a hot junction of a thermocouple at which the electromotive force of the thermocouple attains its maximum value when cold junction is maintained at a constant temperature of $0℃.$ Hence, for a given thermocouple neutral temperature is a constant.
