A good voltage regulation of a transformer means________________?
Correct answer: B. output voltage fluctuation from no load to full load is least
- A. A good voltage regulation of a transformer means
- B. output voltage fluctuation from no load to full load is least
- C. output voltage fluctuation with power factor is least
- D. difference between primary and secondary voltage is least
- E. difference between primary and secondary voltage is maximum
Explanation
Good voltage regulation means the secondary-terminal voltage changes very little between no-load and full-load conditions. Thus, the fluctuation in output voltage is least.
