Thanks Vapojoe. So theorectomly...I mean theoretically speaking 
, we can have two coils in the same atty with a different resistance for each. Let's say we build a tank with two chambers and each chamber has a different e-liquid, and each e-liquid has its own unique characteristics such as viscosity, sweetness, etc.., requiring a different amp draw for optimum performance. When vaped at the same time and within the same draw, the combined e-liquids may provide an out of this world experience. Of course we would need an adjustable vapor flow to use the appropriate amount from each tank according to taste in addition to the adjustable air flow, liquid control, etc...this also means we should have a way to adjust the resistance of each coil without having to take the atty apart and rebuild the coils.
ok, I just had another idea for a multiple flavor, multi coil atty where you can have up to 8 selectable flavors that can be activated by a simple push button switch on a single mod...on my way to the lab to experiment

Thanks Vapojoe. Of course I'm an example #1 man. I rotate 10 batteries, and I never run out of power

Yes, you are exactly right! You could certainly create a dual tank setup with a coil of one resistance for one tank and a coil of a different resistance for the other tank. Note that you would technically be using two single coil heads (as opposed to one dual coil head) but as long as you had them in parallel, the rules of dual coil devices I outlined would still apply.

I'd rather not try to understand all of that lol. Have fun tho guys, seriously! we all have different interests

Hey, fair enough! But if there is one thing to take away from this post I would say to remember that if you are at 8W on a single coil, you will need to be at 16W on a dual coil to achieve the result of 8W through each coil.
I have a Uncle who is a retired electronical Engineer. Most of you are cut from the same cloth. I find it easier to just smile nod my head in the right places and say yea from time to time. If I utter the words I dont understand out comes the pencil and paper and several hrs later I go to bed with a headache;-)
But He is my favorite uncle and I love him dearly.
It's all good man, I am positive a lot of people really dig your knowledge on the subject and it is appreciated that you shared it. I am and I am just a noob just trying to get away from cigs. I just push buttons til it works the way I like it and that works for me.Thanks for sharing this, it actually made me laugh! I've had professors who were the same way, and now I've become them!!!

He taught me how to use a mini oscilloscope I got Its cool to compare the mods and play around. If nothing else vaping has taught me some things about DC current and batteries. How cool is that whoed of thought stopping smoking would turn out to be educational;-)
I tried to do that, but the post is currently just over 16,000 characters long and apparently the maximum character count is 10,000 (unless I'm missing something). I'm not sure I could shorten it by that much and still retain the same level of information but I'll certainly try when I get a bit more time!
Good question, and you're pretty much right with your assumption. If you're using a BDC rated at 1.8 ohms, there are two 3.6 ohm coils in there. I've never actually looked at or used any of those charts, and without seeing the one you're looking at it's impossible for me to give good advice based on that chart. That being said, I would personally start with about 5 watts through each coil in a BDC. So if you are using variable wattage, simply set your device to 10 watts. If you're using variable voltage, set it to 4.3 volts (roughly 10 watts). I would consider this the lower end of the spectrum, so if it's not enough vapor for you or the flavor you're looking for, just turn the wattage or voltage up slowly until you find your sweet spot.
Works out a little strange in the real vaping world. Figure the voltage/wattage both as a single coil (3.6ohms), and as a dual coil (1.8ohms), and then split the difference. Bet you hit it perfectly on the first try.

Thanks for the feedback dev! Hopefully that iClear30 works out for you!
Oops! After reviewing the post to shorten it for a blog entry, I realized I made an error. That should say that total current is equal to voltage divided by total resistance (at least the formula was correct I suppose). Sorry if this caused any confusion! The blog entry can be found here.

ok, your post addresses what happens electrically and of course this is all true, but I think when you say that a single 8watt coil will vape exactly the same as a dual coil setup at 8 watts is not exactly true. yes you have the equivalent of 2 coils running at 4 watts each but what you are not addressing is the fact that you may now actually have 4 times the surface area, assuming duals are built with the same gauge as the single was.
example, I run a single coil 1/16th dia. of 8 wraps 28ga for a coil at .8 ohms, vaping at 20 watts. now I go and change up to duals, 16 wraps each, still 1/16th dia still 28 ga for a dual setup thats now still .8ohms but I now instead of having only 8 wraps running at 20 watts I now have 16 and 16 for a total of 32 wraps now running at 20 watts. the vape is not the same at all, even though they are both same ohms both same watts. the dual setup will produce more vapor and be a bit smoother, maybe a bit longer heat up time but the duals with dual wicks holding twice as much juice will not be the same as the single coil.
another thing that could be addressed if you really want to get technical when we get into rba's is chamber size vs coil and air chamber density. it is commonly accepted that a smaller chamber will produce better flavor enhancement, an atty with a slightly larger chamber may not be as flavorful as the same setup in a smaller chamber atty, but now if you go and run duals in that slightly larger chamber you are effectively halving the amount of volume per coil so flavor is greatly improved even if all else remains the same electrically, so just saying that duals are going to be the same as a single unless you double the wattage is really not entirely accurate I think.
