2 cards from this section. Quick, good the night before a test.
What does τ represent in an RC circuit?
Think about how resistance and capacitance relate to timing.
Name one application of RC timing circuits.
Consider where you have seen timed events.
What does τ stand for in RC timing circuits?
Think about how this relates to charging and discharging.
True or False: RC timing circuits can only be used for pulse generation.
Recall the various uses mentioned earlier.
Calculate the time constant for an RC circuit with R = 220 kΩ and C = 10 µF. How would you adjust R or C to double the time constant?
Remember that τ = RC and doubling one affects the other too.
Design an RC circuit that has a time delay of 15 seconds. Discuss the practical considerations when choosing R and C.
Make sure to use reasonable standard component values to achieve desired time.
