  • How to measure resistance of a Potentiometer?

    Handy tutorial! I'm curious though, what determines the resistance? Is it greater exposure between the pot.'s sliding plate and the contact, or less? (Does greater surface contact generate more resistance, or less?)Also, I find it a bit confusing that you use positive and neutral as voltage designations for the multimeter leads, shouldn't it be positive and negative? Technically ground isn't neutral, it's an alternate positive (as in positive charge, not positive voltage relative to another voltage) where electricity can flow in case of a short.
