Re: where use all three terminals on a potentiometer?

I have used two of the three terminals to vary the resistance for
controling the gain or amplification for audio. I am newbie and
haven't used the three terminals all at the same time. I guess it
might be used to split current or perhaps some usage for varying the
voltage drop? Is there any circuit for hobbyist to build to use all
three terminals for some sort of cool device?

You use all 3 terminals for a potentiometer, most popularly in your
instance as a volume control.

Using only 2 terminals as a volume control will result in a limited
range that will never be fully off.
