Im not sure what you mean by airy, but you will get less vapor with a higher ohm assuming you use the same voltage or same ecig if its not variable. The higher the ohm number the more resistance though, to electricity. So basically the lower your ohm rating the more power you will get if the voltage does not change.

If you are using a non variable battery 2.5ohms will be a very light vape.

"resistance" is electrical term - not air flow!
And it's measured in ohms. So BY DEFINITION, 2.5 is "more resistance" than 1.2.
But again - that isn't related to air flow! It's got to do with how much power the battery will need to put out to make the coil heat up, and that can effect the flavor.
ProTank's air flow can be changed by using a different coil HEAD (there are a couple that fit in there - and the little tube is different), or by replacing the "BASE" - there have been a couple versions of the ProTank base - one has more little airholes - which are right by the threaded part you screw in.

Are you trying to make it MORE or LESS "airy"?
And for the right coil resistance - what kind of battery do you use?

oh boyee...

Ohms symbol Ω is the measurement of resistance in a conductor to the flow of electricity (similar to a kink or drag of water in a water hose)
Voltage symbol V or E depending on whatever formula you are looking at is the measurement of the PUSH the electricity has on it in that same conductor (similar to the water pressure of water in the hose)
Current symbol I or amps is the measurement of the actual amount of electrons in that conductor (similar to the amount of water flowing thru said water hose)

The resistance of the coil in conjunction with the voltage of the device determines how much "power" or watts is available to turn electrical energy into heat energy, the efficiency of the heat energy to transfer to a liquid medium in order to cause to boil (vaporize) is dependent upon many things

High watts = more heat energy however too much heat energy = converting the oils of the e-juice into carbon (thus the nasty licking a charcoal briquette) taste

Low watts= less heat energy which means it will take longer to heat the e-juice to make steam (vaporization)

In order to mathematically calculate power you use a formula called OHMS LAW E/I X R, Voltage divided by Current times Resistance (rememeber in highschool when you said "when will I ever use this algebra crap" well...howdy doody) :)

Since you know the voltage of your rig and the resistance of the coil you can calculate current flow, current flow can then be converted to watts (aka power)

Raise the voltage or lower the resistance is how you tweak your "power" of your rig (thus the VV (variable voltage) rigs)

Using the math is just a starting point (it also gives you a operational parameters that your rig/coils should be able to safely handle)...ultimately you will learn how to tweak your rig or coils in order to get the best vape...just remember you CAN overdrive your rig, resulting in burnt out coils, heated/shorted explody batterys...

Want a laugh? I have a bachelors n mathematics, law and Masters in business from Yale New Haven.
I'm 32 and I'm finally using some math skills... Wonderful.
My wife does college level calculus "for chit's n' giggles"

I'm lucky I can figure out the better deal between 10oz of something or 14oz of something at the grocery store...IF I can find it (I admit...in the store I call her and ask here where it is in the store!)

I was a 2841 in the Marines

Funny how some of that works, I can do almost any equation under the sun but once your put a formula infrin if me I seriously have to think. Weird. How long ago did you discharge?

lol. In your case OP, you can probably just remember that V=IR and also P=VI

The rest of the wheel is derived. (they used W for watts instead of P, and E for volts instead of V in the wheel above). You see different variables all the time because P, W, E, V are used for different things depending on context and also physics uses V and A for other stuffis. Grrrr. Also, multimeters have an ohms symbol on them rather than say "ohms" or "R" or "resistance".... so Ω = ohms.
Good post WarHawk.
