Challenge Problems
Push your limits with challenges.
Question 1
Design a simple capacitor filter circuit that reduces ripple for an AC source. Provide values for the capacitor based on a given load.
💡 Hint: Use the formula for ripple voltage to find the appropriate capacitance value.
Question 2
If a capacitor charged to 12V is suddenly connected to a load drawing 50mA, how long will it take for the voltage to drop to 6V, given that the capacitor has a capacitance of 1000µF?
💡 Hint: Calculate R first, then use the equation for discharging exponential.
