sible, to attain a fairly high temperature for the hotjunction. For the zinc-iron couple, the vessel E may be a cruciblecontaining solder with the couple in an oil capsule. The e.m.f. isusually small, and is therefore conveniently measured in micro-volts. 1018 MAGNETISM AND ELECTRICITY CHAP. The… … Fig. 959.—e.m.f.-temperature curve for zinc-iron couple. Fig. 959, would lead to great complexity. Another method of repre-sentation due to Prof. Tait is therefore usually adopted. Instead ofplotting e.m.f. against temperature, the e.m.f. with unit difference oftemperature between the junctions is…
