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 $(T)$.
  1. $T_n=2 T$
  2. $T_n=T_i-T$
  3. $T_n=T_i+T$
  4. $T_n=\frac{T}{2}$

Solution

$\because T_n=\frac{T_C+T_1}{2}$ and $T_C=0^{\circ} \mathrm{C}$ $\therefore T_n=\frac{T_1}{2}$ .
