Theory and calculation of alternating current phenomena . Fig. 154. In Figs. 155 to 158 are shown diagrams, giving the points £0 = impressed , assumed as constant = 1000 volts,E = consumed by impedance,E^ = consumed by resistance (not numbered).The counter of the motor, Ei, is OEi, equal and parallel-££0, but not shown in the diagrams, to avoid complication. The four diagrams correspond to the values of power, or motoroutput. P = 1,000,P = 1,000P = 6,000P = 9,000P = 12,000 6,000, 9,000, 12,000 watts, and give:46 < £1 < 2,200, 1 < / < 49 340 < El < 1
