I have noticed that the only difference between a potentiometer wired as
a variable resistor, and a potentiometer wired as a voltage divider, is
that one terminal is either left unconnected or is connected to ground.
But what is the actual difference in the wiper (output) signal between a
variable resistor and a voltage divider? is it just that a variable
resistor will never reach 0V, or is there more to it? thanks!
