For a thermocouple, the neutral temperature is 
and the temperature of its cold junction is 
. If there is no deflection in the galvanometer, the temperature of the hot junction should be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
When there is no deflection, then this temperature is called inversion temperature. It is given by the relation
Where 
is temperature of cold junction 
and neutral temperature
