Electrical Engineering XYZ MCQs
Direction of the current in the compensating winding is XYZ to the direction of current in the armature conductors. Here XYZ implies:
- Exactly opposite
- Same
- Either of these
- None of the above
Correct answer: 1. Exactly opposite
Explanation: In electrical engineering, compensating windings are often used in DC machines to counteract armature reaction, which is the magnetic effect produced by the armature current in a generator or motor.
When the compensating winding is said to be “XYZ to the direction of current in the armature conductors,” it means that the current flowing in the compensating winding is oriented in a manner that opposes or compensates for the effects of the armature current.
So, if the current in the armature conductors flows in one direction, the compensating winding current flows in the opposite direction to counteract the magnetic effects, hence the phrase “XYZ to the direction of current in the armature conductors” means “Exactly opposite.”
