Question
The thermo e.m.f. E in volts of a certain thermocouple is found to very with temperature difference θ in oC between the two junctions according to the realtion
E = 30θ -
The neutral temperature for the thermo-couple will be
E = 30θ -
The neutral temperature for the thermo-couple will be
Options
A.450oC
B.400oC
C.225oC
D.30oC
Solution
A given E = 30θ - 
For natural temperature,
= 0 or 30 = 2 
⇒ θ =
= 225oC.
For natural temperature,
= 0 or 30 = 2 ⇒ θ =
= 225oC.Create a free account to view solution
