Question

When the cold junction of a thermocouple is maintained at 0${}^o$C, the thermo emf 'e', generated by this thermocouple is given by the relation.

Answer 1

When the cold junction is at 0°C and hot junction is at t°C, then thermo emf developed is given by :
$e=\alpha t+\beta t^2$
where $\alpha$ and $\beta$ are parameters of material used.
