Exam-style question
Try this first
In a Zener diode circuit, what is the effect of increasing the reverse voltage beyond the breakdown voltage?.
- A.The diode will stop conducting
- B.The current will increase significantly
- C.The diode will behave like a regular diode
- D.The voltage across the diode will decrease
Model answer
What a good answer should say
- The current will increase significantly
Explanation
Why this works
Once the reverse voltage exceeds the breakdown voltage, the Zener diode conducts current, and the current increases significantly while the voltage remains approximately constant.
