Ohm/volt/watts noob confused,

[DaxFX]

Ok guys here is my confusion.. Why everyone want more volts? Is not the same a low ohm/volt setup then a high ohm/volt if we endup with same watts? What is diferent i have see a couple of tables like the one on discountvapers that shows you can get same watt with high or low volts, do i will have a diferent result same watt higher volter?

I just got my TWIST a week ago and i have not the need to crank up the volts to 4.8v

Thanks,

Yep. Same watts.

The only difference is that some mods are prettier than others.

There is no practical difference. As you guessed, it all comes down to watts... well, sort of. It really comes down to atomizer coil temperature but that really only becomes relevant with rba's where you can put in different wire gauges. In other words, thicker wire will need more watts than thinner wire to get to the same temperature. However, thicker wire is lower resistance but also has more surface area available to atomize from per inch. You can't really worry about that for standard equipment like cartomizers and pre-built clearomizer heads.

Sorry, maybe too much info. But yeah, low ohms/volts basically gets the same results as high ohms/volts. The chart you are referring to works really well for normal stuff; it comes from this equation: W = V x V / R . Just keep in mind it doesn't work for RBA's, as you can get away with much higher wattage without burning your juice or wick, and the payoff is a big increase in vapor and flavor.

Okay, I'll admit it. I was completely happy with my ego. The only reason I bought my I pro was because it is so pretty. Really, I'm not kidding. That's true.

But aside from the pretty, pretty mods, another advantage of VV is being able to adjust for a particular juice. Some juices taste better at different wattages than other juices.

Im looking into a mod but only for cosmetic reason and the novelty of a screen too see volts, ohm, remaining battery etc, being a gadget lover you can understand me (im in love with techy eVic). my TWIST is doing extremly well, i also notice that not all my flavors are good at same wattage my cherry and strawberry have a very strong sweet candy on high wattage so i dial down a bit the volt and perfect fruit flavor, by the other way looks like my coffe expresso likes a higher volt range, comparing both on same ohm. So a VV is not a bad idea, im glad i went into that route

The advantage of VV you can simply fine tune your taste by changing volts instead trying diferents heads ohm,

So what i cant understand is those ugly boxed mod why would some1 endup vaping on that they are so ugly,

More volts does NOT equal better flavor/vapor. It all hinges on what you have screwed onto the top of your battery. If you slap a 1.5 ohm low res carto onto your battery and crank it to six volts, have fun vaping burning electronics. Bigger sometimes isn't better.

I'm horrible at math and graphs. Easiest way i learned? Multiply your Ohm resistance by two. That should offer a home base. That being said, I am still a low-voltage vaper. Anything at two Ohm resistance I vape at 3.8 volts/6.5-7 watts. But that's me, and not you. I always say, start low first, then go high. Stop at your sweet spot and leave it there.

I add 2 to the resistance to get my "on the fly" voltage starting point, then dial up or down to taste. 2 + whatever the resistance of the device is, and setting the voltage at the resulting number ≈ 8 watts. 8 is a bit high for most of my juices, but, as I said, it's just a starting point.

ETA: Rocketpunk's method comes closer to what you'll likely end up vaping, but I add faster than I can multiply.

But what about amps? That's a vital piece of the equation, is it not? If you vape 10w at a low voltage or a high voltage, the amount current isn't going to be the same with both. You can't boil it all down to watts, you know? That's what counts for you, but my god, think of your batteries!

I use a couple of different methods:

Multiply your Ohm resistance by two add two devidebysevencalculatethesquarerootofpiandmultiplybythemegellianofcapricorn.

Or... just take a puff and if you want more vapor, twist voltage a bit higher and if you want more flavor, twist voltage a bit lower.

Oh, dear Lord. I can't even get volts, ohms, and watts straight, now you want to add amps to the mix??? I'm going to hide in the corner. JK

I agree, twist the dial till it tastes good. Usually that's on the lower half of the dial with clearos soI don't worry too much about the rest.

You left out E=MC^2, and in conjunction with the sine(32) divided by the tangent(X), then don't forget to add in the quadratic result of amps, volts, watts, and the assumption that your supply is infinite and without resistance.

Result now is (easily done in your head) E=Mc^2 * (sine(32)/tangent(x)) + (Ax^2+Wx+V). Where a = amps, w=watts and V =Volts, and of course (not to insult anyone) E is the resulting voltage setting, and x is whatever you want it to be.

At least this how I derive my desired Voltage setting. With practice this can be calculated in less then 1 second.

While on paper watts are watts, in use there is a difference. LR atomizers seem to give a denser vapor than the same over all wattage using sr or hr.

It's all interrelated and the numbers go up and down as you change the variables. A good analogy is a garden hose. The volume of water flow equates to current flow (amps). The size of the hose represents resistance (ohms). A smaller hose presents greater resistance to the flow of water and a larger hose presents lower resistance. Water pressure is analogous to voltage. The more you turn it up, the greater the flow (amps). Watts is simply a relational comparison of flow to the combination of pressure (voltage), flow rate (amps), and resistance (ohms).

This web page compares the analogy of water pressure and voltage variables.

A good way to see how the variables change is this web page. There's a calculator that lets you change the variables and see how the others interrelate.

Sadly, my brain won't function that way. Like I said, I'm horrible at math, and when I say horrible, I mean horrible. I have to go by taste alone. Honestly, I've never really thought about amperage at all. But thanks for mentioning it, because now it's something else I can add to my understanding.

One of my favorite one-sentence quotes from Chappelle's Show, the skit "The Mad Real World".... they're all making fun of the dorky white kid and Tron shouts out, "What's the square root a' this apartment?! Aa! Aa! Aa!"

If it burns my lips or burns my juice, I turn it lower. That's all I got!

And if that doesn't work, try some new juice or a new atomizer design.
