A Zener diode with a breakdown voltage of 6 V is used for voltage regulation. If the input voltage varies widely, which statement is correct?
- 1The Zener diode becomes forward biased to handle the excess voltage
- 2The load current remains completely unaffected regardless of the load resistance
- 3The Zener current will vary to maintain a constant output voltage✓
- 4The output voltage fluctuates directly with the input voltage
Correct answer
The Zener current will vary to maintain a constant output voltage
