Hello I was wondering how to test a wire's resistance per foot. So it would be easier to gauge how much twistid wire I would need with out building a coil first then testing.
Would cutting a foot of it and holding my multimeter to each side work?

You'll get better results with a longer section of wire, the meters we use aren't super accurate for such small lengths so the longer the wire the more accurate you can expect the reading to be.

I'd suggest 1m or 3' then divide accordingly.

yes the more wire, the less resistance since there's more wire to carry electricity
wouldn't it be the more wire the more resistance as it would be a longer trip from pos+ to neg-
which is why you can do 5 wraps of 24g and 10 wraps of a thinner gauge and get same ohms?

don't mind the post I'm drunk
