If the load resistance decreases in a Zener regulator, then Zener current ______________?
Correct answer: A. Decreases
- A. Decreases
- B. Stays the same
- C. Increases
- D. None of the above
Explanation
When load resistance decreases, load current increases; with the series current approximately fixed, less current remains for the Zener. Thus the Zener current decreases.
