Question 1 [12] A shunt d.c. motor has an armature resistance of 0.5 ohms and field resistance of 100 ohms. When a voltage of 120V is applied to it, it reaches a steady-state speed of rotation of 1200 rpm and draws 40A. a) Now a 1.5 ohms resistor is connected in series with the armature. Calculate the motor's steady speed and the current it draws under the same load. [9] b) Explain what will happen to the motor's speed if the field resistance is creased: no calculation is needed.
