Let's talk watts vs volts

[wyetterp]

Ok, so I got a V2 provari & curious about a few things. I'm sure some with a better wattage knowledge then I can answer.

If I take a 1.5ohm & push it to 9watts, would if produce the same & be equivalent to a 3ohm pushing 9watts? Meaning could you be able to tell a difference, or is there any difference? I've used several different ohm cartos, but for some reason prefer 3.0ohms at higher volts vs lr as mid volts. Then again I've mixed in duel coils which muddle things even more.

Also, I've also been in a self debate whether it would be better on the device & battery to push a lr at higher volts or a sr or hr, at even higher volts. Ideally keeping things around 9 watts.

Thanks!

To get 9 watts using a 1.5 ohm load would be roughly 3.7 volts. 9 watts with 3 ohm load would be roughly 5.2 volts.

Same heat but the coil is different, a higher ohm coil is usually longer (more wraps) so you're getting that heat over more area. Think of a stove adjusted to the same temp using the small burner and the large burner.

In my experience they are different, LR is a great way to simulate it if you don't have a higher voltage device but I prefer higher voltage with higher ohms. In theory the coil should last longer also and pull less current from the battery increasing battery life.

Ok, that make a lot of sense. Thanks. I didn't think about the size of coils & surface area.

If you won't mind, I'm tucking that one away for future discussions like this. I have another from AttyPops using different sized motors in cars on the freeway that works pretty well too, but yours is a more fitting way to explain it.

Here's a little thread from the Inter-Vets Forum. Maybe it'll help a little bit. Or maybe not.... :

You might like this one too:

Just punch in the volts and ohms in the provided spaces, then hit "calculate" to get the watts. And the amps, too.

Thanks dekalbave. For some reason it wouldn't let me view the like-vape thread. Said I didn't have permission.

Anyway, I understand the calculations. Just really didn't understand why a lr carto or atty doesn't seem to hit as well to me as a sr pushing the same amount of watt's. I was just thinking, all things being equal, that 9 watts on a lr would seem exactly the same as 9 watts on a sr. But the sr at said watts just seems better to me.

I think the analogy of the burner size explains a lot.

Hmmm. well I guess you have to be a veteran just to even read it. Not sure I agree with that policy, though.

Anyway, sorry if I misunderstood you, and thought you didn't get the calculations. Might help someone else though, you never do know.

I'll earn my stripes some day. I am going to try & dig around to find it. Thanks.
