ETERMINATION OF LOSSES. The differences between the curves plotted in themanner just described will give the losses due separatelyto iron and friction in the djmamo, and these losses mayconsequently be directly plotted in a second series ofcurves. The curves in Figs. 73 and 74 will show theform… … 900 1300 1000 1100 1200 Revolutions per minute. Fig. 73.—Curve.s oi Watts Spent in Driving Dynamo.
