thermo-couple AB has the hot junction




A thermo-couple AB has the hot junction at 240oC and the cold junction at 10oC. Calculate the thermo-e.m.f., neutral temperature, the temperature of inversion and maximum possible thermo-electric e.m.f. With respect to lead the thermo-electric coefficients PA = 17.34 and qA = -00.487 for metal A and PB =1.36 and qB = + 0.0095 for metal B.
