Question 1
What characterizes a Zener diode?
- It conducts only in forward bias
- It maintains a constant voltage in reverse bias
- It acts as a regular diode at all times
💡 Hint: Think about how Zener diodes differ from regular diodes.
Question 2
True or False: A half-wave rectifier uses both half-cycles of the AC waveform.
- True
- False
💡 Hint: Remember the definition of half-wave versus full-wave rectifiers.

Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit using a Zener diode and calculate the necessary resistor to achieve voltage regulation with a minimum input of 12V and a Zener voltage of 5.1V.
💡 Hint: Remember to consider the maximum load current your application might require.
Question 2
Compare the ripple voltages produced in half-wave and full-wave rectifiers for the same load. How does the rectifier type affect the overall output quality?
💡 Hint: Evaluate how many cycles each rectifier utilizes to determine the ripple effect.
