Correct option is A
· A 3-point starter is designed to provide a gradual increase in voltage to the motor's armature, which helps in preventing excessive current flow during startup.
· It has three points of connection: the armature, the field winding, and the supply line.
· This type of starter is suitable for both shunt and compound motors because it includes connections for the field winding and the armature, allowing it to control the starting current effectively.
· Therefore, the correct answer is: (a) shunt and compound
