How to measure resistance of a Potentiometer?
A potentiometer works where the connection between leg 1, and leg 3 are connected by a semi-resistant plate/ribbon etc, and leg 2 is connected to a dial that moves along it, gathering a voltage where it has less or more resistance. leg 1 - leg 3 being the maximum resistance.
i dont mean to be rude, but just from personal usages, they always take a little bit, dependent on the pot.
hi, i am doing an experiment where i have use a 10k pot. but when i keep the circuit on for few hours then i found my pot. became faulty and the value i set previously has change.Can any one tell me why my pot. fails?
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.
So, if I understand it. A 15k potentiometer turned to its minimum would be o resistance. So, if you wanted a pot to read 60 ohms at the minimum, you would put a 60 ohm resister in line on the 15k pot? You would at least reach a min of 60 ohms but w/o calculating it would not reach 15K at the max.
