Exam-style question
Try this first
Which characteristic of a Zener diode allows it to maintain a constant output voltage?.
- A.High forward resistance
- B.Zener breakdown voltage
- C.Low reverse resistance
- D.Temperature coefficient
Model answer
What a good answer should say
- Zener breakdown voltage
Explanation
Why this works
The Zener breakdown voltage is the specific reverse voltage at which the Zener diode begins to conduct in reverse, allowing it to maintain a constant output voltage despite variations in input voltage.
