Then, asthe angle </) changes, the point P will describe a circle aboutthe point C, for the line CP is of constant length, being equalto A [the electromotive forces (effective) of machines A and Bare of course supposed to be constant and their phase… … Fig. 192. Draw the line ef, Fig. 192, through the point O makingwith OC the angle 6 as shown, then OQ, the projection ofOP on the line ef, represents the power oiitput P of machineB. This is shown as follows : The angle between B and Eis equal to ^ -|- {BI^ and it is also equal to Q plus the…
