Challenge Problems
Push your limits with challenges.
Question 1
You have a Zener diode rated at 5.1V and your input voltage can vary from 10V to 15V. Calculate the series resistor needed if the load current could be a maximum of 10mA.
💡 Hint: Consider the worst-case circuit configuration for your calculations.
Question 2
Compare the ripple voltages for a half-wave and full-wave rectifier, assuming the same load and input. Explain why the full-wave rectifier has lower ripple.
💡 Hint: Review the formulas for ripple voltage in both configurations.
