If the cold junction of a thermo-couple is kept at 0°C and the hot junction is kept at T°C then the relation between neutral temperature (Tn ) and temperature of inversion (Ti ) is :
Answer & explanation
Correct answer: option 4
Since : Tn = \(\frac{T_i + T_c}{2}\)
Tc = 0
[Tc = 0°C = temperature of cold junction]
