The nature of armature reaction in a 3-phase synchronous generator depends on the nature of its load power factor.
Match List-I (nature of armature reaction) with List-II (Nature of load) and select the correct answer:
List-I
A. Cross-magnetizing
B. Partly demagnetizing and partly cross-magnetizing
C. Partly magnetizing and partly cross-magnetizing
D. Completely demagnetizing
List-II
1. Zero p.f. leading
2. Zero p.f. lagging
3. Unity p.f.
4. Leading p.f. impedance
5. Lagging p.f. impedance1
