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 𝑅1 and 𝑅𝐿 are 200 Ω and 1 kΩ, respectively. What is the range of Vi that will maintain the Zener diode in the ‘on’ state?
Ans: 24 V to 36 V
Solution:
For the zenor diode to be on minimum voltage across it should be 20V.
