Dual coils absolutely have a different set of rules that apply to them. My explanation is strictly applicable to single coils, and was only given to show that the rule of adding 2 to whatever resistance coil you are using is not a truly accurate measurement of anything. It is also not accurate for dual coil devices or any other known electronic device. I wasn't trying to be a jerk about it, my engineering background and natural curiosity simply prompt me to analyze such theories.

You're the one who gave the dual coil example in your post. No where did your original statement indicate you were speaking of single coils, yet now you say that's what you were talking about. 
A 1.5 ohm dual coil is actually two 3.0 ohm coils in a clearomizer or cartomizer. The battery or the ohm meter doesn't differentiate the resistance as two coils, but only reads 1.5 ohms as if it is a single coil, and the battery supplies current to both coils equally.
The rule of two is just a simplification of Ohm's Law for variable voltage for novices. I not picking a fight. Just stating facts.

I don't think he was talking about two coils wired in parallel... Two separate coils...
2 Ohm coil @ 4V = 8W @ 2A
4 Ohm coil @ 6V = 9W @ 1.5A
I think the intent was to stress that the +2 thumbrule doesn't always yield ~ 8W

Ah, this seems to be a simple misunderstanding. You misread my post. Allow me to quote myself...
"Yes, I am well versed in Ohms Law. I have a Bachelor of Science in Electronics Engineering Technology. Your theory about taking the resistance number and adding 2 to find the right voltage has some holes in it. By your logic a 2 Ohm coil should be vaped at 4V and a 4 Ohm coil should be vaped at 6V. This results in 2A of current through the first coil and only 1.5A through the second coil. Furthermore, it results in the first coil being operated at 8 Watts and the second coil being operated at 9 Watts. Thus, your theory falls apart rather quickly. But I digress, I'm not here to discuss Ohms Law. "
Nowhere in that statement did it say I was referring to dual coils. I see how you may have gotten confused by my use of "first coil" and "second coil", but I was in fact referring to two separate coils. I thought this was made obvious by the fact that I was applying a different voltage drop to each coil (I've never taken apart a dual coil device but I assume the coils are wired in parallel in order to achieve the same voltage drop across each coil). Nonetheless, I was referring to single coil devices.

...sorry. Couldn't resist. Please don't hate me.
Edit: Drat. I thought he was talking about dual coils too.
Baditude will still forget more about carto tanks than you will ever learn, so there's that, at least.

My misunderstanding.
I would never use VW even if my device had it. I adjust my voltage to taste for individual flavors, not for a certain set wattage.

I have a EE as well, and I'm wrong all the time... Thankfully I have a full head of grey hair and can blame my plethora of mistakes on old age! And a second degree in IT... When I'm wrong on one, I claim my expertise in the other field... Haha!

He can have the carto tanks, I'll stick to my trusty BCCs
We have to get ready for all the bacon tacos tomorrow! Time to print more lettuce!

I just want to know if bacon is used as the meat within a traditional taco shell.... OR THE TACO SHELL IS MADE OF BACON!!
The shell is made of bacon... You only get them if you own a ProVari... You must join the cult!
We are weary because to us, having been here awhile, it's an old argument, that most of us don't care about.
For me personally, I have other VW devices. The way I vape is to use carto tanks. I can build a coil and I have RBA's but I just don't have the time for stuff that is fussy. With carto tanks, the resistance is the same as I always use the same cartos. I don't normally feel the need to tweak my settings. So, for me, VV and VW end up being the same.
ETA: One of my VTR's is being returned due to an issue with the VW not reading resistance correctly. It arrived to me that way. So, I gotta agree with the less features, the less issues. Never had a ProVari issue in the 10 months I have had them (I have 3).

and I thought that having a Mr. Ocelot in the forums would create less confusion.
It's your own fault, Ocelot. You picked a gender neutral username. Suck it up and drink your Kool-Aid.
Edit: though your profile picture is definitely femme fatale...with a dash of feline.

I suppose, but I often wonder what part of Princess and Baroness in my signature is confusion. I let Infanta slide.
