How do I use an Ohm's law calculator?

[zapped]

My sweet spot changes from 5 watts to 8.5 watts depending on the device I'm using, the juice I'm vaping, and my mood, zapped.

Not to mention the fact that many, many vapers use set-voltage batteries. So let's say, using your calculations, somebody using a 3.2-3.3v eGo battery should use a 1.2-1.3Ω atomizer? But that would most certainly kill his or her battery in no time flat. The "add two and then adjust to your liking" method is not only inaccurate but may even be dangerous, particularly with eGo-class batteries.

The Ohm's Law Calculator is a good thing. And it really isn't that hard.

The OP stated he was using a Provari in the beginning of his post. For those of us who arent overly complicated the equation works just fine. It was never meant as a hard rule but as a jumping off point to get the user within range. Ive found it incredibly accurate with my own Provari.

If you bother to look at the wattage chart posted previously it also puts someone using a 3.2 volt battery at 1.2 to 1.3 ohms so I fail to even see the reason for your argument here.

BTW Ego batteries fully charged are 3.7 volts.Thats what 1.7 volt LR atties like the Resurrector were originally made for. 3.2 volts is almost a dead battery.

Keep It Simple Stupid is a motto that I try to live by in regards to vaping as much as possible.I dont envy your mood, device and juice changes.

The act of smoking was incredibly simple...you opened the pack, lit your cigarette and inhaled. I dont see where vaping HAS to be complicated to be enjoyable.

But it isn't complicated at all. I like my tobaccos at higher Wattages, fruit and delicate flavors on lower wattages etc. Once I know what wattage goes with what flavor (and atty), I just aim for that wattage. I don't have to look and scroll and finetune anything every time I change an atomizer, for instance.

Of course, I understand your point. I don't use that calculator anymore--I pretty much know what I like. But I found it very helpful when I was a beginner.

Besides, the OP's question was: "How do I use an Ohm's law calculator?" I just answered it.

I just showed him a different way to do it. Were shooting for the same target here just coming from two totally different angles. I used my Provari the first time I quit smoking for a year without even knowing or caring what wattage I was at.

It isnt needed with a Provari. You could start at the lowest setting and bump it up in .1 volt increments until you find your sweet spot, all through trial and error. We used to call that "dialing in your juice".

According to the chart above I like my juices with a 3ohm cartomizer at 8 watts. Thats interesting to know but the magic number on a Provari for me is 5.0 volts.

I just answered OP's question to the best of my ability.

Whatever works is good!

3.7 volts at 1.7 ohms is 2.17647 amps. That's really pushing an eGo battery.

The person who created one of the Safe Vaping Power Charts wrote the following article on finding your sweet spot using resistance, voltage, and watts. Reading it may help a newcomer to understand the terms better.

It is....but you have to remember that vaping has come a long way in just 5 short years. 1.7ohm and under Low-resistance atties were first created to be used with 901 and Kr808 batteries with an average charge of 3.7 volts. They can go as high as 4.2 volts on a brand new freshly charged battery and the Ego shares many of the same characteristics except in a somewhat larger form factor.

Moving up to a VV or VW mod offers a lot of benefits over "battery style" e-cigs, not the least of which is the ability to use higher resistance atties/cartos/clearos and prolonging the battery life.

Provari recommends 2.5ohms or higher in its cartos because to go under that is setting up a potentially dangerous situation where the battery is discharging at an extremely high rate. There is a potential for catastrophic failure there that shouldnt be ignored.

That being said, people do it all the time with sub ohm RBAs and ultra low resistance cartos on battery-style e-cigs. I didnt say I recommended using a 1.70hm cart with an Ego just that its possible and well within the safe range according to the wattage chart posted earlier.

People will always try to push themselves and their equipment to the limits. Its human nature to do so. In the case of electronic cigarettes and mods, I think its better to find something that delivers the vape you want with plenty of room to spare either way.
