The corona is considerably affected by which of the following _______________?
Correct answer: D. All of the above
- A. Size of the conductor
- B. Shape of the conductor
- C. Surface condition of the conductor
- D. All of the above
Explanation
Corona depends on conductor size, conductor shape, and surface condition because these factors affect the electric-field intensity at the conductor surface. Rough or irregular surfaces intensify the field and make corona more likely.
