A dc series motor is connected to a load. The torque varies as the square of the speed.With the diverter-circuit open, the motor takes 20 A and runs at 500 r/min. Determine the motor current and speed when the diverter-circuit resistance is made equal to the series-field resistance. Neglect saturation and the voltage drops across the series- field resistance aswell as the armature resistance.
