Yokes with rectangular cross-section are used for_______________?
Correct answer: A. small capacity transformers
- A. small capacity transformers
- B. medium capacity transformers
- C. large capacity transformers
- D. any of the above
Explanation
A rectangular yoke section is economical for small transformers because the magnetic flux is relatively low and simple construction is sufficient. Larger transformers generally use stepped or cruciform sections to reduce iron and improve material utilization.
