Challenge Problems
Push your limits with challenges.
Question 1
Design a Zener voltage regulator with a specified input range of 9V to 12V and a load of 100 ohms requiring a 5V output. Determine the appropriate values for R_S and the expected I_Z at no load.
💡 Hint: Remember to calculate I_Z using the maximum load scenario.
Question 2
Explain the effect on output voltage if the load suddenly decreases after a stable Zener voltage is established.
💡 Hint: Consider current behavior under varying load conditions.
