Factors affecting oms.

So for practical purposes, it might be best to build several different types and gauges to see what you prefer

That's funny As I was making my first coil set last night,, with inferior kanthal I might add,,, I made a couple just to test ohm results
from a single gauge and varied coil diameters lol .. Had NO plans on vaping any of them .. Just recording my results for reference...

Good thinking! Keeping good notes will save a lot of time and frustration in the future

 

[edyle]

in a DC circuit one does not have to account for inductive reactance.
however if your variable voltage or wattage device is using pulsed DC
than depending on pulse width and frequency it could induce an
inductive resistance.
i haven't heard of that happening but it could explain some of the
stranger problems i have heard here.

Good point!
That inductive impedence could be the reason some people say their flat dc output tastes different from their PWM regulated device at the same supposed voltage.

I'm surprised (or maybe I Missed it) to see No Mention of Material Type?

For the Same Wire Gage and Length, Different Resistance Wire Materials can have Different Resistances.

Certainly true, Zoid. While Kanthal A1 is what's generally used, now, with the introduction of the temp controlled batteries, Nickel comes into play. BIG difference

I'm don't keep up much with what is "Trending" Coil Wire wise.

I just know at one time, many people were into NiChrome60 as the Be-All-End-All alloy. And as you mentioned, high Nickel alloys are needed for Calculated Temperature in these New 3rd Generation Chipsets.
