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

A thermo couple is formed by two metals X and Y metal X comes earlier to Y in Seebeck series. If temperature of hot junction increases beyond the temperature of inversion. Then direction of current in thermocouple will so
