Share:
- 1The Zener diode becomes heavily forward-biased to manage the excess voltage.
- 2The load current remains absolutely constant regardless of load resistance.
- 3The Zener current varies significantly to keep the output voltage nearly constant.✓
- 4The output voltage fluctuates linearly with the input voltage changes.
Correct answer
The Zener current varies significantly to keep the output voltage nearly constant.
