I'm working on some projects that may or may not wind up in the book. I looked for an old concept I was taught as a tech, the RC time constant, and can not find it anywhere in the AAC book. Am I missing it, or is this an oversight?
According to "Electronic Communication", 3rd Edition, by Robert L. Shrader, Tc = RC
Tc is in seconds
R is in ohms
C is in farads.
1 Tc is 63% of a charge, or change in voltage on a cap from charging/discharging. 5 Tc is a full charge (basically an arbitrary figure, but a good one).
There is a similar concept for inductors, the LR time constant, which is expressed by the equation of Tc = L/R
The difference is the inductor deals with current, while the capacitor deals with voltage.
Both of these equations are simplifications of the calculas equation that actually determines this. I'm working on determining an inductance using the LR time constant, which led me down this path.
If it is not in the AAC book I really feel it should be added.
