Challenge Problems
Push your limits with challenges.
Question 1
You have a Zener diode rated at 12V. If your maximum load current is 40mA and the input voltage varies from 15V to 20V, calculate the suitable series resistor to protect the Zener.
💡 Hint: Identify values for V_Z = 12V, I_L = 40mA, and adjust for I_Z.
Question 2
Evaluate the performance of your Zener regulator. If the output voltage drops significantly under high load conditions, what modifications can you make?
💡 Hint: Explore the balance between load regulation and heat management.
