Correct answer: B. lap wound
- A. wave wound
- B. lap wound
- C. delta wound
- D. duplex wound
Explanation
Equalizer rings are used with lap windings to equalize the voltages of parallel paths and prevent circulating currents caused by unequal generated emf. Wave windings normally do not require equalizer rings.
