Challenge Problems
Push your limits with advanced challenges
Design a simple DC power supply circuit using a full-wave rectifier and a Zener diode. Include calculations for the necessary resistors and Zener voltage based on maximum and minimum load conditions.
💡 Hint: Use principles covered in class and consider component ratings.
Given a load that requires a steady output voltage of 5V from a Zener regulator, calculate the series resistance needed if the supply voltage is variable between 10V and 15V, knowing the Zener holds at 5.1V.
💡 Hint: Consider both minimum and maximum currents in the calculations.
