RC Circuits |

The time constant of an RC circuit is the product of its resistance and capacitance. For ** R** in ohms and

*t = RC*

**5 RC Rule of Thumb**: A capacitor charges or decays to within 1% of its final value in 5 time constants.

**Rise Time**: Time required to go from 10% to 90% of Vout.
