Question 3Electricity & Electronics - Assistant Engineer

The correct answer is C. The "M1, M2, and M3" motor leads are connected to the rotor windings via slip rings and brushes, while the "T1, T2, and T3" motor leads are directly connected to the stator windings. This is the typical configuration for a wound-rotor induction motor, where the rotor windings are accessed through slip rings to allow for external resistance or voltage control to be applied, while the stator windings are directly connected to the power supply. The other options are incorrect because they do not accurately describe the connections shown in the illustrated wound-rotor induction motor. It is important to understand the correct lead connections in order to properly operate and maintain this type of motor.
