Question

question 9 (6.7 points)
technician a says that a wye - type stator, in an alternator produces more maximum output current than an alternator with a delta type stator. technician b says that a wye - type stator, in an alternator produces less maximum output current than an alternator with a delta type stator. who is right?

1. technician a only
2. technician b only
3. both technician a and b
4. neither technician a nor b

Explanation:

In an alternator, a delta - type stator produces more maximum output current than a wye - type stator. This is because in a delta connection, the phase windings are connected in a triangular fashion, and the line current is \(\sqrt{3}\) times the phase current. In a wye connection, the line current is equal to the phase current. Since the maximum output current is related to the line current (for a given phase current capacity of the windings), the delta - type stator can provide a higher line (output) current. So Technician B is correct.

Answer:

1. Technician B only
