100 cms. long, and the resistances AC, CD, DB,and EF are each equal to the resistance of AB, then, when the balanceis attained for the point, say 35, upon AB, this corresponds to a p.d.proportional to 35 if the other contact is at A; but to 235 if at D, and435 if at F, etc. This method of… … I I I I I I ■ I I Il IT-T- ■■■ I r-1- FiG. 112. has a resistance equal to the whole of ah, and so arranged that thepotential terminal from the source under measurement may be con-nected directly to a or to the junction l^etween any of the fourteencoils, by means of the rotating arm. ti is a key…
