A few other notes when you go looking for a pot. Theres a couple major things to think about when purchasing a potentiometer from anywhere. These include whether you want an audio taper or linear taper pot and also whether you want "10-turn" or single turn pot.

A linear taper pot has the same change in resistance for every degree it is turned, while an audio taper pot normally has different ranges of change of resistance. All the applications Ive used pots for in FIRST have primarily used linear taper pots.

Now onto the amount of turns. This is where it will normally come down to the application the pot is being used for to choose which type is best. If what you are measuring the amount of turn on goes less then 360 degrees a single turn pot normally is what you would use and would have more precision for small amounts of turn. A "10-turn" pot is like the name suggest a potentiometer that will turn more then one complete turn and is used normally on devices that can do more then one complete rotation.

[Al or anyone please correct me if im wrong and i searched how-stuff-works for more in depth explainations but it seems they dont haves pots described there.]
