is again taken as the starting point, and themeasm-ed voltages are set off radially from the circum-ference of the circle at the angles at which they wereactually measured. Fig. 88 shows the same results plotted so as to give thedifference of potential between successive pairs of seg-ments, instead… … Fig. 8.—Curve of Potential Rodnd the Commutator.(Note.—This diagram is not reproduced exactly to the same scale as Fig. 86.) In order to explain the significance of curves such asthat showTi in Fig. 88, it will be useful to refer to a seriesof curves obtained theoretically by Mr. C. P. Steinmetz.*…
