i. You are working with the DC motor and the motor is accelerating. Suggest a way that can optimally control the speed of the motor. Explain the method and how it is a better way. ii. What type of DC motor should be used when the load connected requires a higher starting torque? Precisely explain and draw the relevant circuit. iii. What will happen to a DC series motor if the load is suddenly thrown off the motor? You can explain with any mathematical reasoning. iv. What effect will the load have on a DC shunt motor with significantly high armature resistance? v. For the four-point DC starter kit, what will happen if the series resistances are connected in reverse order. Draw and explain how this combination is better than the 3 points started.
