Single coil for a kayfun using 26g with 8 wraps 2.5 mm id gives me 1.1 ohm on the meter. I'm curious how the ohm would change if the coil were larger as in 3 mm, or smaller 2 mm, If the same wire and wraps were used. Your thoughts please.

Welcome to ECF, banjer...
Resistance is based on wire length and thickness. Wrap count increases or decreases as the ID becomes smaller or larger... but has no effect on net resistance.

To answer your question, if you enlarge the coil ID your ohms will increase. If you shrink the coil ID your ohms will decrease.
Back to you, Bob.

In general, the more metal bridging the gap between the positive and negative poles of a battery, the lower the resistance.
Never saw that site before. But it sure beats the hell out of the app I've got on my phone.

It's my primary bookmark. Not 100% accurate for wrap counts but gives people an awesome baseline to go off of.
Yeah I couldn't build coils without it -- and that 'Ohm's Law' section lets me figure out, from my wattage and resistance, what my actual voltage is, and also lets me figure out how many amps my setup is drawing.
Anyone know what the rated amp limit is for ego-type batteries? I don't sub-ohm or anything close to it, but I've had my Kayfun on my ARO Winder lately, with a coil that's 1.8Ω; I'm just wondering if that lil Winder is actually safe to use, with that coil.
