- 1The output voltage fluctuates significantly with the input changes
- 2The Zener current varies to keep the output voltage nearly constant✓
- 3The load current remains perfectly constant regardless of load resistance
- 4The Zener diode becomes forward biased to regulate the voltage
Correct answer
The Zener current varies to keep the output voltage nearly constant
