Zener diode is used to regulate the voltage supply because, while using a Zener diode
Options
- Avoltage remains constant, even when current varies much
- BBoth voltage and current remain constant
- Cvoltage varies much, but current remains constant
- DBoth voltage and current vary together
Correct answer
A. voltage remains constant, even when current varies much
Step-by-step solution
In a Zener diode, voltage across it remains constant even when current varies much or wide range. This property of the Zener diode is used to regulate the voltage supply.
