For Copper-iron (Cu-Fe) couple, the thermo e.m.f. (temperature of cold junction =^(@)C ) is given by E=(14theta-0.02 theta^(2) ) mu V . The neutral temperature will be

For a thermocouple, the temperature of inversion is that temperature at which thermo e.m.f. is

Find the emf developed per .^(@)C temperature difference of an iron constantan thermocouple , given that thermo emf's of iron and constantan against platinum are 16 muV and -34 mu V "per" .^(@)C temperature.

Assertion : Thermocouple acts as a heat engine. Reason : When two junctions of thermocouple are at different temperature, thermo e.m.f. is produced.

The cold junction of a thermocouple is at 0^(@)C . The thermo e.m.f. epsilon , in volts, generated in this thermocouple varies with temperature t^(@)C of the hot junction as epsilon=6+4t-(t^(2))/(32) . The neutral temperature of the thermocouple
