Challenge Problems
Push your limits with challenges.
Question 1
Design a Zener regulator circuit for a Zener diode with V_Z of 7.5V. The input voltage can vary from 14V to 17V. Assume I_ZK is 2mA and the load draws 10mA. What value would you choose for R_S?
💡 Hint: Use the provided formula to ensure adequate regulation.
Question 2
Discuss what would occur in the circuit if R_S were greatly underestimated. How would the Zener's performance be affected?
💡 Hint: Think of how excess can affect sensitive components.
