Stupid question regarding wattage

[Squeak]

To start, I vaguely remember reading a formula which stated that voltage squared divided by resistance = wattage. Don't know if that's correct so please correct me if I'm wrong.
Assuming for a second that I'm remembering it right then if I have my VV battery set to 4 volts and am using a 1.8 ohm coil (off the shelf Aspire bdc coils) in my clearomizer, then I'm looking at 4x4/1.8 = 8.88 Watts or thereabouts, again feel free to remedy my ignorance.

So, my question is based on the above. I'm planning to pick up an MVP2.0 come payday, to relegate my current Ego batteries to backup status, and for VV it's 3.3 - 5 volts, and for VW it's 6 - 11 Watts.

Does that mean it will cap out at 11 Watts even if I'm using the Voltage settings? for example if I wanted to run it at 5 volts with the same coil (not that i'm planning to, just curious) that would put it at 5x5/1.8 = 13.88 Watts (approx).
So will it actually fire at the 13.8ish watts or cap at the 11 Watts stated for the VW?

Also, if I'm missing some crucial information that would destroy the battery if I attempted this please let me know.

Sorry for the rookie question, and thanks in advance for the enlightenment.

The beauty of VW devices is the voltage will be adjusted for the resistance of the device. If you overdue it will be hot and burned. In reality it is easy. Start at 6W and slowly increase until the vape is perfect for you. Set and forget! Nice.

Greetings and welcome to the forum. As the saying goes, the only bad questions are the ones we don't ask (not counting ones asked while under the influence of alcohol ).

Most AVPs (and I believe this includes the MVP) has safety features that will keep the mod from firing under unsafe conditions. If you're using store-bought coils in the normal resistance range, you pretty much can't go wrong.

I am running a 1 ohm nano coil on my MVP right now. I have read that it will cap out the wattss and volts respectively I think. I do know there is a 3 Amp limiter on the battery so no matter what you have set, you will cap out at 3 amps. Does that help?

Just to toss some extra knowledge in the mvp2 has a believe a 2.5amp limit so it would be capped at 4.5v's which is effectively 11 watts. even if you are setting it higher using a 1.8ohm head it will limit the power to what the chip set considers safe which would be 4.5 and below.

to determine the amp load you would simply divide the voltage by the resistance. so 4.5/1.8= 2.5amps

Damn, I was just getting used to Volts and Watts and you had to go throwing AMPS into the mix as well, time to take a night course to learn this stuff.

Aside from that, thanks for the info. I think that's answered my question about whether the output would be capped. I wasn't planning on trying to run anything crazy on the MVP anyway, just curious about what it can and can't do prior to ordering.

Now to go google "Electricity for Dummies" and "Electronics for Dummies" so I can figure this stuff out properly.

That is a good one, LOL
