Why ask about resistance/power? Why not ask amperage instead?

So say I have 2 different builds, on the same atty. And the only difference is that one is built with 24 gauge and one with 28. Ohms, volt, watt, and amps the same on both. That 4 gauge difference will produce more vapor because more of the wick is covered. Correct? I mean it makes sense but i figured the amount of vapor wouldn't be noticeable. I havent built below 26g really and i started on 28 so i guess i should be experimenting more.

YES, experiment more. I use 26awg. It has less resistance so and I get more surface area. Think of resistance in terms of a pipe with water flowing through it. The bigger the pipe (24awg) the easier it is for the water to flow through it; less resistance.

Yes there is a tiny bit of lag for the coil to heat up. 28awg just burns too hot for me on lower ohm builds. I don't like it. On a very practical note, 26awg is so much easier to work with and my screws don't snap it off like they do with 28awg.

So your 24 has less resistance so you can put more wraps on it and get more surface area to produce better flavor and vapor. Try 26awg, it is a great size.

You can get huge vapor at 2ohms and you can get huge vapor at .2 ohms. Most cloud chasers wrap 24awg around a 2.5mm mandral. 3-4 warps then go bananas. Many use parallel coils.

    Unless my google-fu has let me down, a 1200 cc Harley engine typically outputs 45 kW. A 250 cc Husqvarna engine is typically ... wait for it ... 45 kW. :D

    In any case, there is no general way to convert between cc and power (watts). But converting betwen power and heat is trivial, because in a heating element, power is heat.

    Why do you think I chose those two? One is a race bike, and the other a road bike.
    While the power is the same, it's how they chose to get there and what they chose to do with the power that determines performance.

    I could just as easily have said that 10 watts in an old 510 atty won't perform the same as 10 watts in a KayFun, because again, it's how we get there and what we do with the 10 watts that determines performance.

    2 different builds , same atty.
    1 build with 24g and 1 build with 28g.
    same ohms
    same voltage

    yep; same amps and same wattage; correct.

    the 24 gauge is thicker wire; it won't get as hot as fast as the 28 gauge.


    Theorectically because it's the same wattage, it should vape the same amount per second of juice, but the big difference would be the 24 gauge will be slower to start up; sluggish compared to the 28 gauge; or the 28 gauge might seem too hot.

    Or ............. the 24ga to cold.

    ahhhhh ok all of this makes a lot of sense. I still want to experiment with the 24g for the experience. I have a vertical quad coil build that i am being told i will get a much cooler vape from the 24g than with the 28g on.

    That would depend on how long you "pre-heat" the coils before taking a hit.

    A typical way to use 'fat wire' is to Listen to the crackling to determine when it's up to temp.

    Hmmm. That's probably why I prefer regulated vaping over sub-ohming. Using a fat coil and lots of amps, listening for the sound of the coil, and adjusting your draw according to the sound/feel, simply does not give you the same effortless control over the temperature as you get with a regulated mod and a faster coil.

    Never thought of it that way before. Sub-ohming requires you to focus on what is happening in the atomizer. With a regulated mod you can just adjust it to your liking, and after you've set it, you can vape away without any effort.

    Both approaches have their appeal, but for me, most of the time, regulated vaping is so much more convenient.

    YES this is why i reaaaally want to get a Coupor T5 within the next couple weeks. VW sounds so appetizing

    All I'm wondering is why this and the other very good thread about VV/VW isn't in one of the building forums. I mean, some stuff gets jumped on and moved, and threads like these, although very informative, are rather meaty for a "general discussion" area.

    My head hurts again. :(

    IMO, the last thing any of the modding forums (if that's what you meant by building forums) need is this stuff!

    Although early here , I still think its pretty nice to see people discuss the topic. Its the basics of vaping and clearly their are still plenty people confused about these concepts. I think most have intuative experience but few that can explain it properly as a whole.
    Probably due to the amount of variables involved. Firstly the volts and resistance to a certain watt and level of amps via a wire length and gauge resulting in a certain temperature let loose on a liquid mix with a certain consistency absorbed and wicked via some wicking material.
