Exam-style question
Try this first
Zener regulator ? identify the regulation condition. Use this to support: Explain duty cycle qualitatively.
- A.Zener regulator: the Zener diode maintains an approximately constant voltage when reverse biased beyond breakdown for Astables.
- B.Zener regulator: uses forward-bias rectification only.
- C.Zener regulator: claims current is zero in breakdown.
- D.Zener regulator: confuses regulation with amplification.
Model answer
What a good answer should say
- The correct option is Zener regulator: the Zener diode maintains an approximately constant voltage when reverse biased beyond breakdown for Astables.
Explanation
Why this works
This is the best answer because the Zener regulator context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Astables.
