Exam-style question
Try this first
How does the Zener diode differ from a regular diode in reverse bias?.
- A.It does not conduct any current
- B.It conducts current at a specific reverse voltage
- C.It has a higher breakdown voltage
- D.It can only conduct in the forward direction
Model answer
What a good answer should say
- It conducts current at a specific reverse voltage
Explanation
Why this works
Unlike a regular diode, which blocks current in reverse bias, a Zener diode allows current to flow at its breakdown voltage, making it useful for voltage regulation.
