amps or watts

[Doc Diego]

Perhaps you mean Voltage=Current x Resistance? Power = V x I = I² x R.

Was thinking the same thing today, just hadnt had a chance to get back on. Normally i'd remember I squared R is power without deriving it. Sigh. Insomnia, pain and math don't mix. You are correct and I was lost in space there. Kudos for the catch!

Thanks for your replies everyone, there's a lot of good information here. It also helped me to sort out what I'm trying to understand about this. I thought that amps were the sole difference between lower and higher ohm coils, but there's a lot more to it than that: surface area of the coil, how fast it heats, etc. that has the effect on how it vaporizes your juice. So much more to learn, but at least I'm having a lot of fun with this new hobby.

I guess I was trying to figure out which has the better vape: a lower or higher ohm coil (given the same watts and a proper VV device that can power both options). Or even simpler, which would you tell a rookie to buy: LR or SR cartos (or which HH357 resistance)? From the responses so far, I suspect that there's not an easy answer to that...

Ahem. Get the SR ones (see my earlier post as to why when you get past theory).

As to theory, not to mess up your taco, but the ingredients and construction matter too. So the viscosity of the juice will change the "wicking" speed. And the VG content vs the PG content changes the vapor and TH.

OK, so then we qualify the question "for the same juice" on different ohm coils. Then "using the same wicks". Then further "Using the same type of wire".

The ohm's law thing is a ball-park figure that determines watts. However, since there's more surface area in a longer wire (thus higher resistance for that same guage wire) it's hard to say for sure what happens. It's a real thermodynamics question and plays to what % of the watts actually goes into the juice, and how fast can the juice wick and vaporize?

So there's so many variables that you have to "mess with it". Like billbeckusa said. For example, I wish it were as simple as watts. Most newbies have wicking problems with stuff at whatever watts. And juice gunks coils. Wattage too high is as bad or worse than wattage that's too low.

Meh. The watts thing is the simplest math you can put on it. Everything else has a lot of variables and gets complicated real fast. Watts don't tell the whole story, and we often over-simplify because in the end you just "dial it up or down" to tweak the vape (at least with vv).

I kind of agree, but I find it interesting anyways and I am sure some new vapers do too.

Yup! I'm a new-ish vaper and love this stuff!

Thanks guys, for giving me an interesting read!
