Q. The temperature at which thermal electric power of a thermo couple becomes zero is called
A) Inversion temperature
B) Neutral temperature
C) Junction temperature
D) Null temperature
Explanation
(b) Thermo-electric power $P = \frac{dE}{d\theta};$ at $t_{n},\ E \rightarrow$ maximum
So $P \rightarrow$ zero
