Armature reaction in a generator results in_____________?
Correct answer: A. demagnetisation of leading pole tip and magnetisation of trailing pole tip
- A. demagnetisation of leading pole tip and magnetisation of trailing pole tip
- B. demagnetisation of trailing pole tip and magnetisation of leading pole tip
- C. damagnetising the center of all poles
- D. magnetising the center of all poles
Explanation
In a generator, armature reaction weakens the leading pole tip and strengthens the trailing pole tip. This distorts the main flux and shifts the magnetic neutral axis.
