tric diagram, according to Professor Tait, for the principalmetals. Lead is the metal taken as standard, since this does notshow the Thomson effect. The abscissae represent temperaturesin centigrade degrees, and the ordinates the thermo-electric heightsiu microvolts (or millionths of a volt) per… … Fig. 135. the area to be calculated is that of a trapezium, such as mnmn(Fig. 1.34); it is sufficient to multiply half the sum of the twoparallel sides by their distance apart. This distance is the differ-ence <2 - <j of the two temperatures ; half the sum of the parallelsides is equal to the…
