Correct me if I'm wrong (and I probably am)...

I'm doing a lot of reaserch planning on investing in my 1st mod soon and have narrowed it down to a provari v2 or zmax, with the provary having a slight edge because of the build quaility and me not being light on anything. A comparison of the two isn't the basis for the post, though. It would seem the one main gripe any provari owner has if they have any is it's lack of abilities when it comes to running dual coil atties, cartos, etc. I have never run DC anything but i have a couple of rba's on the way and was going to start experimenting with building coils and know you cand build dual coils on [the phoenix].

Isnt 1.5 ohms the same whether there are 2 coils or one? the resistance is the same so is it the amps required to heat two coils greater even if the constructed resistance of the atties the same?

from all i've read it seems the max load for the provari on a 1.5ohm single coil atty is somewhere around 5 volts (which to me seems like way too high of volts, but if that's your thang, lol) If i run a 1.5ohm dual coils at that same 5 volts is the vape much lighter, not as hot or robust, if you will.

And just for my own understanding of dcc's to get a 1.5 ohms resistance is that 2 coils at .75 ohms?

thanx peeps!

Thanks for asking this, I'm needing clarification too. My understanding at this point is that two 3.0 ohm coils connected in series? add up to make a 1.5 ohm total resistance atomizer. Seems like it should be the same thing, in terms of how your mod reacts, as a 1.5 ohm single coil. Far as I know it's all about the amp limit of the mod.
I just got my first Provari and the build quality and performance are excellent. Zmax looks really interesting but personally I will wait to see others experiences with them before buying one.

I just tried to google some articles on resistance and ohms law, and almost had an brain aneurisym. orz

Without feeling a need to grok things I went for reliability and consistancy. Oh and this chart

http://www.ecigadvanced.com/community/wp-content/uploads/2012/07/power.jpg

shows the potential melting point of nichrome wire for 1.5ohm resistance @3.6 volts (8.64watts). Looking at some other charts the ranges are all in the 3.6-3.75 range.

I'm a fair bit sketchy on Dual coils and ohms law, stopped using duals since I only had egos at the time and they just don't perform well on egos.

As to the question about resistance, duals are odd for us non-electricamally minded folks. Here's somethign that may help answer

Doesn't really work the way you would think. A 1.5ohm DCC has two 3ohm coils. Charge life is measured in mAh (amps), and a 1.5ohm carto will draw the same amperage regardles of how many coils it has. However only half of the total will be used by each 3ohm coil. So a 1.5ohm DCC will not be as hot at a given voltage as a 1.5ohm SCC, but will produce a larger volum of vapor.

So you have to set the voltage higher to get the heat, not more vapor.

Dual coils would have less Wattage or Power at each of the coils. This will produce a weaker vapor at each of the coils. A 1.5 ohm dual coil carto is (2) 3 ohm cartos in parallel. What that does is at 3.7 volts is give you just enough power to each of the coils to start to vaporize vg, and produces a weak vapor. For variable voltage users taking a 1.5 ohm dual coil carto up to 4.5 to 4.8 volts will usually produce a satisfyng vape, providing the carto can wick the liquid you are using fast enough to the coils.

Dual coils have the coils in parallel. That is why you get 1.5ohms of resistance from 2- 3ohm coils in parallel.

thanx peeps. I found an ohms watts amps volts converter that also shed some light on it. here's the link:
