Q. In the circuit shown, the breakdown voltage and the maximum current of the Zener diode are 20 V and 60 mA, respectively. The values of π 1 and π πΏ are 200 Ξ© and 1 kΞ©, respectively. What is the range of Vi that will maintain the Zener diode in the βonβ state?
Ans: 24 V to 36 V
Solution:
For the zenor diode to be on minimum voltage across it should be 20V.
