How much juice can a regular guitar pot take?

[ThreeChordWonder]

A friend needs a pot for his kids science project or something. 9 volt battery.

Will a regular 250k pot take the volts and say a single amp?

Honestly asking for a friend. This time...

I believe most guitar pots are rated at 1/4W.
You'd probably want something more heavy duty for a full one Watt.

Then again, for a short duration it might be okay.
I'd keep it on a heat-resistant surface and well away from anything that could burn or melt, though.

Okay thanks. Probably not a good idea then.

[ThreeChordWonder]

Yeah, worried about that too...

Why not buy a cheap rheostat at Home Depot or Lowe's? Or do you need the extra post?

Do you know what they are trying to do with a potentiometer and 9V DC?

No but isn't a rheostat basically the same thing as a pot but with only 2 legs?

This article seems to do a good job of explaining their differences and similarities. The potentiometer is useful because it is a nice, self-contained voltage divider; thats how the volume controls in our guitars work.

I'll check that out later for sure, thanks.

What's TCW trying to accomplish?

A friend's kid has a science project to do.. I don't know the details,, but probably something to do with batteries and bulbs. I was thinking of donating a used guitar pot, but it was late at night, and I was "a bit tired" at the time.

That's all.

Why don't the 9 volt batteries in our guitars damage the pots?

Just imagine a guitar with 48V actives...

As LPB has said, a guitar pot will be fine with a 9V battery.
