Thermal Properties Of Matter Ques 47
47. If the cold junction of a thermo-couple is kept at $0^{\circ} C$ and the hot junction is kept at $T^{\circ} C$ then the relation between neutral temperature $(T_n)$ and temperature of inversion $(T_i)$ is
[2007]
(a) $T_n=2 T_i$
(b) $T_n=T_i-T$
(c) $T_n=T_i+T$
(d) $T_n=T_i / 2$
Show Answer
Answer:
Correct Answer: 47.(d)
Solution:
- (d) Since $T_n=\frac{T_i+T_C}{2}=$ Neutral temperature
$T_n=\frac{T_i+0}{2}=\frac{T_i}{2}$
$[T_c=0^{\circ} C=$ temperature of cold junction $]$
