and A are at the samepotential, if they be joined the total electromotive force roundthe circuit at the three junctions is 5 + 8 — 13 or zero. On the chemical theory of course the metals when incontact are all at the same potentials; the differences occurbetween the portions of air in the immediate… … Fig. 190. It has been tacitly assumed throughout the above that theconductors are throughout at the same temperature. If ina circuit of two metals one junction is maintained at a highertemperature than the other, then as we have already seen acurrent flows round the circuit. See Section 182. 316…
