In an unregulated power supply, if input a.c. voltage increases, the output voltage _______________?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains the same
- D. None of the above
Explanation
An unregulated supply has no feedback to correct input changes, so a rise in transformer or input AC voltage appears as a rise in the DC output after rectification.
