Helical windings are used in________________?
Correct answer: B. power transformers
- A. distribution transformers
- B. power transformers
- C. shell type transformers
- D. none of the above
Explanation
Helical windings are suited to the high-current, relatively low-voltage windings commonly found in power transformers. Distribution transformers generally use simpler cylindrical or layer arrangements.
