e resultant E.M.F.is also given (in our case 14°), we can draw the linesrepresenting e^ and e,. The current line must be at rightangles to e„ and can now be drawn in, its length beingdetermined from the equation i = 242 c above given.To find the power corresponding to the selected position WORKING… … 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 w.^. Similarly, if weproject the current line on the vertical, and multiply the 270 ELECTRIC TRANSMISSION OF ENERGY. scaled amount with 1^100, we obtain the…
