For V-curves for a synchronous motor the graph is drawn between:_______________?
Correct answer: D. field current and armature current
- A. armature current and power factor
- B. terminal voltage and load factor
- C. power factor and field current
- D. field current and armature current
Explanation
A V-curve shows how armature current changes with field current at a fixed load. The minimum armature current occurs near unity power factor, giving the characteristic V shape.
