Losses which occur in rotating electric machines and do not occur in transformers are___________?
Correct answer: A. friction and windage losses
- A. friction and windage losses
- B. magnetic losses
- C. hysteresis and eddy current losses
- D. copper losses
Explanation
Friction and windage losses require moving mechanical parts, so they occur in rotating machines but not in a stationary transformer. Magnetic and copper losses can occur in both types of equipment.
