9-14, A de series motor operates at 750 rpm with a line current of 100 A from the 250-V mains. Its armature- circuit resistance is 0.15 N and its series-field resistance is 0.1 1. Assuming that the flux corresponding to a current of 25 A is 40% of that corresponding to a current of 100 A, determine the motor speed at a line current of 25 A at 250 V.
