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.
