Help with understanding potentiometers?

[QUOTE="madgorillaz15, post: 4691903, member: 500851"] Hey Simon, OK, I think I'm starting to understand how they work a little more. And you're correct, I've never seen a potentiometer before, much less use one. I'll absolutely do what you suggested once I have access to some wires and a multimeter (I'm snowed in at the moment). So regarding what you first said, for #1, in this case since x has a fractional value then x = theta/120 (since max angle is 120). And since the max resistance is 100 k-ohms, I am thinking the equation should be: R(θ) = 100 kΩ * (θ/120). For the next part, how do you suggested I go about making the circuit? I know that the input voltage needs to be 5V, and that one of the resistors (if there needs to be more than one) has to be R(θ). But should it be that output voltage increases with the angle or the other way around. And I how would I know where to the resistor(s) and the positive and negative supply for the op amp? Sorry for the further questions, but I already really appreciate the help you've given me. Definitely feel a little bit better about the question right now. [/QUOTE]
