Challenge Problems
Push your limits with challenges.
Question 1
A Zener diode is rated for a maximum current of 50mA and operates at 5.1V. If the total circuit current is 100mA, calculate the series resistance needed to ensure the Zener diode does not exceed its current limit.
💡 Hint: Break down the circuit calculations step by step, and don't forget to use the correct voltage for V_in.
Question 2
Design a voltage regulator utilizing a 12V source and a Zener diode of 5.1V. Specify the design values for R_S to ensure proper operation under load and verify power dissipation.
💡 Hint: Apply the design equations for Zener circuits and check load conditions thoroughly.
