New to the forum! I was hoping someone could answer a question for me regarding ohms, volts and watts !?!?!

Hey all,
I'm hoping to pick the brain of some of you out there. I have been vaping for about a year now. I had v2 stuff before. Now I have a provari and I really like it. I use boge cartomizers mostly and am happy with them. My question is this. What is the difference between using a 3ohm carto @ 4.75volts making 7.52 watts or using a 2.4ohm at 4.25volts making 7.53watts ... so on and so forth. Is there any reason to vape at higher voltage if the wattage is the same. I do enjoy say vaping my menthol at a higher total watts than I do my fruit type flavors but is there any benefit to using higher ohm carts and turning up your voltage if you are achieving the same cartomizer watts?

Thanks a bunch!
Troy

I wondered the same thing for a long time, then I read a thread that explained it nicely. Unfortunately I don't know where it is anymore.

Anyway, 7.5 watts is 7.5 watts, true. But in order to get to a higher resistance given the same guage wire, that wire needs to be longer. Longer coil wire = more surface area to vaporize your juice.

Also there is a difference in amps. A lower ohm carto draws more amps to achieve the same wattage. I'm no expert, I just learned this by playing with a ohms law calculator. Your 2.4 ohm carto would be drawling 1.77 amps and your 3 ohm would be drawing 1.58 amps. Now as far as what that means.... I dunno. I would think it would mean a lower ohm carto would drain your battery faster. Correct me if i'm wrong.

Yes. For the same wattage, higher resistance and higher voltage draws less current, which is easier on your batteries.
Also, higher resistance uses thinner wire in the coil, with more wraps, and that vaporizes a larger area of wick and more juice.
