The thermo emf of a copper-constantan thermocouple with one junction at `0^(@)C` and the other at `t^(@)C` is given by the relation `varepsilon=at=(1)
The thermo emf of a copper-constantan thermocouple with one junction at `0^(@)C` and the other at `t^(@)C` is given by the relation
`varepsilon=at=(1)/(2)bt^(2)`
where `varepsilon` is in `muV, a=41 mu V.^(@)C^(-2)`. If the thermo emf developed is 5.5 mV, find the temperature of the hot junction.
