Challenge Problems
Push your limits with challenges.
Question 1
Design a half-wave rectifier circuit using a PN junction diode and calculate the average DC output voltage given an input AC voltage of 10V (RMS).
💡 Hint: Recall how to convert RMS to peak voltage and then how to find the average DC output.
Question 2
Analyze a circuit involving a Zener diode with a breakdown voltage of 5.1V. Calculate the necessary series resistor to ensure the Zener diode operates in its breakdown region at 100mA load current with a 12V supply.
💡 Hint: Mangage the safety of the circuit, ensure to calculate for maximum Zener current.
