power given to the motor, and the short-circuit current /^is given by the equation „ In a similar manner we see that the output P of the motor in Fig. 355is equal to OB. I. cos ^j, which is exactly equal to the output P of the genera-tor, after deducting the I^.Ra loss in the armature, viz.… … Fig- 357 y is here the angle by which the e.m.f. lags behind the backward pro-jection of the terminal pressure vector. We must now draw curves to show graphically how the power varieswith the angle y. As in Figs. 340 and 341, so here in Figs. 357 and 358,circles are drawn passing through 0 and…
