Electrical Engineering XYZ MCQs
Synchronous reactance of an alternator represents:
- Field winding reactance
- Armature reactance and leakage reactance
- Reactance operating at synchronous speed
- All of these
Correct answer: 3. Reactance operating at synchronous speed
Explanation: The armature reactance represents the opposition to the flow of alternating current in the armature winding, while leakage reactance accounts for the leakage flux and the associated reactance. Together, these two components make up the synchronous reactance, reflecting the impedance that the alternator presents to the flow of current at synchronous speed.
