The load voltage is approximately constant when a Zener diode is ________________?
Correct answer: D. Operating in the breakdown region
- A. Forward biased
- B. Unbiased
- C. Reverse biased
- D. Operating in the breakdown region
Explanation
A Zener diode provides voltage regulation when reverse biased in its breakdown region, where large current changes cause only a small voltage change. Reverse bias alone, below breakdown, does not provide effective regulation.
