2.) A 220 V dc shunt motor has an armature resistance of 0.5 ohms and is excited to produce constant flux. At full load, the motor runs at 1000 rpm, taking an armature current of 40 A. If the resistance of 0.8 ohms is inserted in series with the armature, determine speed regulation at the full load, Ans.: 19.048%
