What's better than POT?
protokatie:
Ok, got your attention, so get your head out of the bong:
I have an answering machine that has its volume potentiometer pretty much a burned out old hippy. It is hard to get it to stay at a volume level, esp one that is audible. I was thinking that since I only need the thing to be loud, that I could short across the the contacts, but this brought me to an obvious question: What is the minimum Ohms of this POT?
I have never actually tested a POT with an Ohm meter, so I have no idea what the low end is (IE is it .001 Ohm, or .1 Ohm, etc?). Besides, I have no way to test this particular one, as it is way too messed up to do the job, it just sits there and does whatever it wants to.
What I do know is that this POT is rated for 9V-12V DC... And well, thats about it.
Any general rules of thumb for what the low end of resistance is on these small POTs? Should I just go with a .5 Ohm or 1 Ohm resistor? Or would a direct wire be safe (in that case I would just duct tape some wire to each terminal on the pot).
After I get my answer, you may commence with the jokes...
danny_galaga:
Hmmm, don't most pots start at zero ohms? and then its 0-100, or 0- 10k etc...
I would be inclined to try a few resistors if you are going to dispense with the pot. Try a 100 ohm and see how loud that is. Then a 10 ohm etc...
Cakemeister:
What Danny said. You might let out the magic smoke if you just jumper the thing.
protokatie:
Hmm, OK, thats what I was leaning towards. I guess I will pick up an assorted pack of resistors the next time I am at radio shack.. Thanx
Ed_McCarron:
If its a 3 terminal pot, you MAY be able to read its total resistance - if only the wiper is munged, measure resistance across the outer two terminals. You may get a reading.
Be sure to replace it with an audio taper (logarithmic) pot.
