A half-wave rectifier has an input AC peak voltage of 12V. Calculate the average output DC voltage. If a load draws 300mA, what would be the ripple voltage if a filter capacitor of 470µF is used?
💡 Hint: Use the average output voltage formula and apply the ripple voltage calculation based on load and capacitance.
Design a circuit using a Zener diode to maintain a 5V output from a variable input of 9V - 12V. Calculate the resistance needed for the series resistor if the Zener knee current is 1mA and it can handle 20mA maximum.
💡 Hint: Calculate values considering both minimum and maximum Zener current scenarios.
