Default Capacitors and Potentiometers

In building a driver circuit, how is the capacitor needed calculated? Also, how low in resistance can a potentiometer go? If I have a 100ohm potentiometer, what is the lowest resistance it can give? Thanks

That REALLY depends on the driver. Context clues suggest you're working with a lm317, in which case any capacitance 0.1-10F will be fine.
