Question 311Electricity & Electronics - QMED

The correct answer is A) interchanging any two of the three line leads. To reverse the rotation of an AC, three-phase, induction motor, you simply need to interchange any two of the three line leads. This will reverse the direction of the rotating magnetic field in the motor, causing it to spin in the opposite direction. The other options are incorrect because they do not properly describe how to reverse the rotation of a three-phase induction motor. Changing the brushes or slip rings would not affect the rotation, and changing all three motor leads would not necessarily reverse the direction.
