Ohms are the resistance on the coil, higher number, higher resistance. It's all a matter of preference, of course, but I think the general consensus is the lower the resistance is, the better.
Dry burning is when you charge up the coil while exposed to burn off any excess gunk built up on the coil.

up the voltage or drop the ohms is there a differance?
changing ohms will cause the juice to be cooler or hotter and can effect the amount of vapor

A 2 Ohm coil at 4.4 Volts will produce 2.2 Amps and 9.68 Watts. A 1 Ohm coil at 4.4 Volts will produce 4.4 Amps and 19.36 Watts. The more current(Amps) being used will drain your battery faster. The more Power(Watts) being used will create more vapor.
Thats a great simple answer, what a lot of people wanted to know.
So for example, if I had a tank with 2.0 ohm coil and my sweet spot, (prime vape) is at 4.0 volts. (I have a simple VV device)
If I get a 1.8 coil do I turn the volts down to get the same vape?
And if I get a 2.2 ohm I turn the volts up?
I was hoping to get a simple answer, sorry but I'm just too tired after work to take an advanced electrical course to fully grasp OHM's law. So with those two questions, can I get a plain answer, or do I need to go back to school? I'll understand if its not possible just to get a yes or no to these.
your sweet spot is at 8 watts.
you would turn it down to 3.8 (actual number is 3.79, but i dont think you can dial it that precicely.)
you would turn it up to 4.2 (again, actual number is 4.19)
in the morning look up ohms law and double check my numbers, then use random numbers.
with your evic, hold the scroll wheel (dial? i think of it as a wheel..) to the left to change the display of puff counter/remaining on battery - time/date - volts / ohms. hold it to the right to change between Varible Voltage - Variable watt (better as it adjusts volts finer that you can in VV mode) - RVV (use computer to set changing voltage while firing, such as start high to warm the coil then drop to your sweet spot, or low and end with a warmer vape) - RVW (same thing but watts)
i love my evic. i use 6.0-8w depending on juice.
Yes, that is what I do, OHMS law and I are not on friendly terms, here is a safe vaping chart that might be helpful:
http://www.ecigadvanced.com/community/wp-content/uploads/2012/07/power.jpg
What I normally do is add 2 volts, so if my coil is 2.4 ohms, I set my volts at 4.4 and if my coil is 1.8 ohms then I set the volts to 3.8.
This pretty much gives me the vape I like, sometime I go up a little or down a little , the chart will tell you what is safe.
Very cool, someone is asking questions about what I specialize in. I'm a computer engineer, but majored in Electrical Engineering before I changed over...
Anyway, like the previous post, ohms is resistance, meaning the higher the ohm rating, the less electricity goes through. So putting all this in simple terms...the lower the ohms, the more electricity flows, the hotter the burn (per say). Higher ohms just means there is more resistance, less electricity flow, lower burn in the coil.
I find that I like the lower ohm coils because I want it to burn faster/hotter. One thing though with lower ohms. Because more electricity is flowing through the coil, your batteries will last for a shorter time. So the higher the ohm, the more resistance, less electric flow, you use less of the battery.
Hope this helps...
For more vapour; low ohms or high voltage. Same-same.
Equipmentwise, high ohms and high voltage are better, because this gives you the same watts at lower amps.
Higher amps need thicker wires and can fry circuit boards and wires. This you can see an example on, as high current wires are not very thick and transports a lot of watts. (High voltage, low amps)
Unless youre on mech mods, i'd choose a higher resistance, 2,0+ ohms, and adjust the voltage.

Hi, incoming Rawr
Your "sweet spot" isn't your volts, it's your watts. Volts are a measure of input, what your battery is supplying. Watts are a measure of output, the power that is being produced.
If you have 2.0 ohm coil and the volts set at 4.0 - it is producing 8 watts.
So, 8 watts is your sweet spot. Keep in mind, Twist and Spinner type of batteries adjust in increments of .2; bigger mods (at least mine) adjust increments of .1. Since you said your device is "simple," I'll guess it adjusts in .2.
To (roughly) stay at your 8 watts sweet spot:
1.8 ohm coil/4.0 volts ≈ 8.8 watts
1.8 ohm coil/3.8 volts ≈ 8.0 watts
1.8 ohm coil/3.6 volts ≈ 7.2 watts
2.2 ohm coil/4.0 volts ≈ 7.3 watts
2.2 ohm coil/4.2 volts ≈ 8.1 watts
2.2 ohm coil/4.4 volts ≈ 8.8 watts
These numbers are based on an equation, but we are humans not robots. We vape by taste, not numbers. The only time I pay attention to equations or charts is when I am deciding what resistance attys or cartos to buy. After that, I don't care anymore. I set my device in the range I know I like and dial up or down from there. I don't like all of my juices at the same power level and I have some I prefer warmer or cooler throughout the day. I'm always fiddling with something.
Since your sweet spot is around 8 watts, a simple way to get a starting point is by adding 2 to the ohms and setting the volts to the resulting number; you then adjust to your liking.
2 + 1.8 ohms = 3.8 volts - set the battery at 3.8 volts = 8.0 watts
2 + 2.0 ohms = 4.0 volts - set the battery at 4.0 volts = 8.0 watts
2 + 2.2 ohms = 4.2 volts - set the battery at 4.2 volts = 8.1 watts
2 + 2.5 ohms = 4.5 volts - set the battery at roughly 4.5 volts = 8.1 watts (Roughly, because with a simple VV the marks go from 4.4 to 4.6)
Sorry to be longwinded and repetitive, but I wanted to be clear without shoving a power wheel down your throat. You will notice that I specifically left amps out of the calculation. For those who wish to flame me at this point, I know how to calculate amps, but I don't give a flying fruit bat about amps. I vape, the battery blinks, I charge it, I vape again. When the battery ultimately dies, I buy another one.
When I make toast, I put the bread in then set it somewhere between light and dark. I don't care what the settings do to the toaster.
ETA: Oops! This is really repetitive! None of the other posts were here when I started typing mine.

First, thank you all for answering my question in the simplest way you could. I know it was not a simple question to answer.
When it comes to the equation of ohms a lot of us just see a lot of numbers that are too complicated to deal with. These answers you all posted are just what I needed. Ill be saving this thread for future use.
So thank you all for your help. JIM
