If the cold junction of thermocouple is kept at

0^{\circ} \mathrm{C}

and the hot junction is kept at

T^{\circ} \mathrm{C}

, then the relation between neutral temperature

\left(T_n\right)

and temperature of inversion

(T)

.

Options

A $T_n=2 T$
B $T_n=T_i-T$
C $T_n=T_i+T$
D $T_n=\frac{T}{2}$

Correct answer

D. $T_n=\frac{T}{2}$

Step-by-step solution

\because T_n=\frac{T_C+T_1}{2}

and

T_C=0^{\circ} \mathrm{C}

\therefore T_n=\frac{T_1}{2}
