Challenge Problems
Push your limits with challenges.
Question 1
Design a Zener voltage regulator that outputs 12V using a 15V input. Given a load drawing 50 mA, calculate the resistance of the current-limiting resistor and verify if the Zener diode remains within safe limits.
💡 Hint: Don't forget to check the Zener current to avoid exceeding the maximum current.
Question 2
In a power circuit with a fluctuating input voltage from 10V to 14V, ensure regulation on a load requiring 30mA. How would you configure the Zener setup?
💡 Hint: Always ensure the Zener current remains above the minimum for effective regulation.
