Kapp, Gisbert, 1852-1922 · New York, Van Nostrand · leaf 288
resultant E.M.F.is also given (in our case 14°), we can draw the linesrepresenting es and er. The current line must be at rightangles to es9 and can now be drawn in, its length beingdetermined from the equation i = 242 e above given.To find the power corresponding to the selected position WORKING… … ie^j power given to the motor in watts. This may be plottedto any convenient scale on the radius giving the motorE.M.F. We obtain thus the point w2. Similarly, if weproject the current line on the vertical, and multiply the 270 ELECTRIC TRANSMISSION OF ENERGY. scaled amount with 1,100, we obtain…
