24Gauge Wire Resisdence Question

[BradMccullin]

Hello, I just build a Dual Parallel Coil with 24 gauge Kanthal wire, both coils are 6 wraps around a 7/64" drill bit. it was real fun to build, but I have one of those dumpy ohm readers right now that doesn't go past the tenths place decimal I had 5 wraps on each and it said .2ohms on my reader which leads me to believe it's anywhere from .15-.24 ohms (really a big deign flaw) now I made them both 6 wraps and I still get .2ohms on the reader. I can't remember wether more wire = more resisdance or what the exact equation is, my main question is: making each coil 6 wraps rather that 5 is my ohm reading now higher or lower than with 5 wraps?
P.s. I am using a sony VTC 4 30 amp battery safe down to .12ohms I believe so around .2ohms this build should be safe if I'm not mistaken

Your resistance will be higher with 6 wraps than 5 wraps. More wire length usually means more resistance.

Steam Engine says you should be right around 0.27 Ohms.

Awesome thanks! about to wick this sucker and see what I'm working with

My pleasure, and please please get a better ohm reader or multimeter. Preferably as soon as possible.

1:
If you can't remember whether more wire = more resistance (it does) then you shouldn't be messing with sub ohm coils, and especiall with 24 gauge kanthal.

xxxjust had a 2 hour power failure

yah; I'm back.

So, um, nothing wrong with a
"one of those dumpy ohm readers right now that doesn't go past the tenths place decimal"

they were not meant to measure how far short you were shorting out your battery.
They're meant to measure OHMS, not milliohms.
In fact you're more likely to find testers that measure kilohms than milliohms
In fact you're more likely to find testers that measure magohms than micro-ohms
