If the load current drawn by unregulated power supply increases, the d.c. output voltage _____________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Stays the same
- D. None of the above
Explanation
Increasing the load current increases the voltage drop across the supply’s internal resistance and transformer or filter resistance. Consequently, the unregulated DC output voltage decreases.
