Question about twisted kanthal.

[DesmondTheMoonbear]

I haven't tried this yet, but would like to. So if I twist two stands of 28g together, and build a micro coil as I usually would (around .8 ohms) , is the resistance going to be the same as it would if I built the same size/wrap coil with a single strand? Also, how does the twisted kanthal affect the draw on my battery? I want to be safe while doing this.

w/x wraps at y diameter with a single strand of 28g kanthal = z ohms
w/x wraps at y diamater with 2 strands - twisted, parallel, braided, whatever - of 28g kanthal = z/2 ohms (actually slightly more than that, since the lengths will be every so slightly longer), and thus double (or slightly less, since the ohmage will be slightly more than half) the current.

You're providing two electrical paths where before you provided only one. Two streets for traffic instead of the one. Resistance is cut in half.

I have twisted 32 gage before it basically makes it around 28 ga. If you are getting .8 what you would end up with would be real low...sob will be hot real hot.
