Q/ A de series motor on load operating at 250 V dc mains draws 25 A and runs at 1200 rpm. Armature and field resistances are 0.1 ohm and 0.3 ohm respectively. A resistance of 25 ohms is placed in parallel with the armature of the motor. Determine: (a) The speed of the motor with the shunted armature connection, if the magnetic circuit remains unsaturated and the load torque remains constant, and (b) the no load speed of the motor with the shunted armature connection.
