Question:
Zener diode acts as
Zener diode acts as
Updated On: Jun 18, 2022
- voltage regulator in reverse biasing
- voltage regulator in forward biasing
- current regulator in reverse biasing
- current regulator in forward biasing
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Zener diode works as a voltage regulator under reverse biasing condition. It is based on the fact that in the break down region, for quite large changes in the zener current, the voltage across the diode remains almost constant.
