2 cards from this section. Quick, good the night before a test.
What is the main function of a capacitor filter?
Think about how a ride on a bumpy road feels.
Define ripple in the context of capacitor filters.
Consider what a wave looks like!
What does a capacitor filter do?
Think about what happens to voltage when it’s not steady.
True or False: Ripple is an undesirable component of DC output.
Consider how stable voltage helps electronics work better.
Design a simple capacitor filter circuit that reduces ripple for an AC source. Provide values for the capacitor based on a given load.
Use the formula for ripple voltage to find the appropriate capacitance value.
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?
Calculate R first, then use the equation for discharging exponential.
