Extracted text: A 250 V, 8-poles lap wound D.C. shunt motor has an armatre resistance of 0.5 N and shunt field resistance of 125 2 . The mumber of conductrors of the armature winding is 500 conductors. The motor draw a current of 10 A when the magnetic field is 20 mwb. If rotational losses is 0.2 kW. Draw the circuit diagram and find: i) The armature current ii) The counter e.m.f iii) The motor speed iv) The motor develop torque v) Themotor efficiency
