I'm currently vaping with a 1300 mah vision spinner and protank 2. I'm using the original coil that came with the tank. I have heard that purchasing different ohm coils can affect different things like resistance and taste. I have no idea which ones do what. Please help explain this to me! I need a new coil!

Ohm rating is the resistance of your coil, by having less resistance you will have more draw on your battery and have a hotter vape with more vapor production and vica versa. If you go too low you risk burning up the flavorings in your liquids and dry hits. It's all about finding that sweet spot for your own personal preferences and the battery/mod you are running the coil on.
Overall ohm rating only matters when comparing two different coils on the same battery, what matters when looking at different coils on different batteries is wattage.
Wattage (power) is calculated by P = V^2/R so:
Scenario A: If you have a 3.7v battery with a 2ohm coil it will be P = 3.7^2/2 which is about 7 watts
Scenario B: If you have a 4.2v battery with a 2.5ohm coil it would be P=4.2^2/2.5 which would also be around 7 watts.
These two configurations would both produce vapor in the same manner.
The ohm rating is affected by the length of the wire, the composition of the wire and the gauge of the wire used for building or manufacturing the coil.
P.s. I see you're from Atlanta, I was actually just there for the first time last weekend and really liked it, except the airport has the worst signage!

The way I look at it is:
Lower ohms = lower volts needed
Higher ohms = higher volts needed
But that's just me!
Lower ohms = lower volts needed
Higher ohms = higher volts needed
But that's just me!
ohm is resistance in the coil and it's affected by length and diameter or gauge.
The lower the ohm rating (low resistance), the warmer the vape experience.
The higher the ohm rating, the cooler the vape will be.
I've found that I'll prefer higher ohms on one attachment and lower ohms on different type of attachment. It takes some experimentation and trial & error to find what works best for you.
The following Safe Vaping Power Chart was designed for single coil cartomizers basically, and was only meant as a general guideline at that. But it does help novice vapors not familiar with Ohm's Law to understand how ohms and voltage can affect one's vape experience.

Resistance will also play a role in battery life. Current is what determines how long your battery can be used. When you lower the resistance with the same Voltage, you increase the current. Resistance is measured in Ohms, Energy is measured in Volts, Power is measured in Watts, and Current(I) is measured in Amps.
I pretty much just use these formulas from Ohm's Law to figure out what's going on with electrical functions in vaping:
Watts= Voltage_squared / Resistance
Watts= Current_squared x Resistance
Current= Voltage / Resistance
I pretty much just use these formulas from Ohm's Law to figure out what's going on with electrical functions in vaping:
Watts= Voltage_squared / Resistance
Watts= Current_squared x Resistance
Current= Voltage / Resistance
And to think, I JUST posted a thread and said in it that I didn't know the math to figgure watts out, and this is the very next thread I click on.
So let me brake this down
Watts=Volts X 2 then devided by Resistance (or ohms)?
So if I'm running my USB passthrough at 4.8 volts I would take that X2 and get 9.6. Now I devide that by the ohm resistance of my coil (2.5ohms) and get a total watts of 3.84. Correct?

Ahh ok that's right!! Squared is x itself.
So in my case it would be 4.8 X 4.8 to get 23.04. Then devide the 23.04 by the 2.5 ohms to get 9.216. Thanks for the math class.

While everything y'all have said is correct, I think everybody's overlooking the fact that the OP is using a VV device and I'm assuming doesn't want to get totally bogged down in math. Char, you can get basically any atty for your spinner. For higher resistance (ohms) you'll just use a higher voltage and conversely lower voltage on lower resistance.
If you are anything like me, I needed to hear someone explain this to me. Pbusardo (an absolute trip of a guy) explains ohms and other such things fairly well in his 101 video A PBusardo Video - Beginners Guide to E-Cigs and E-Cig Tech - YouTube
BTW Bad, I love the chart! saving......

Oh wow this is very informative. I have to admit I was getting a little confused by the math. Vapers are smart 
! I think I might go for a lower resistance coil. Do you guys tend to prefer lower or higher? I like being able to draw air easily but don't want to burn my throat! Lower resistance = more vapor?
Thank you all, it amazes me what a loving and helpful community this is.

I like ohm ratings between 1.7 and 2.4, so lower but not subOhm (which is a whole 'nother natter, much more suited for more experienced vapers than I to comment on).
There is a ton of play in the production of vapor. Actually many things factor in like... 1) your delivery method (clearomizers, cartomizers or atomizers) 2) believe it or not, the ratio of PG vs VG in your juice mix matters too (help me out here experts) As I understand it, high PG in a mix makes it thinner and delivers more "throat hit" whereas more VG makes a thicker juice and produces more vapor....and of course 3) the subject of your post, Ohms and voltage.
I am still trying lots of juices and mixes to find my preference. This part is so very personal and very subjective. You may want to buy small qualities of a lot of different flavors and mixes until you find what you like.

Personally, I prefer a cooler vape. I don't need my vapor to be hot like an analog; cooler and smoother like hookah is.Oh wow this is very informative. I have to admit I was getting a little confused by the math. Vapers are smart

I use 2.0 ohm on fixed voltage batteries (mechanical mods) and 2.5 - 3.0 ohm on my regulated mods (variable voltage).
An easy way to find the right "ball park" voltage setting to start out with using a variable voltage mod is to take the ohm rating and add the number "2".
2 ohms + "2" = 4 volts. Adjust up or down in increments to find the "sweet spot".
I don't mean to replace Baditude's chart with my own (his battery fu is greater than mine).
But I like to share this chart because it includes the voltages and resistances that most vapers are likely to encounter as they start to learn the science behind the art of these magnificent devices.
Most Ego and regulated mods will whine about battery voltage below 3.2v and no battery should be charged above 4.2v (some devices can deliver higher voltage even when the battery is partially discharged, but that's a subject of another issue altogether).
Also, I consider anything at 10.0W and above to be too hot and anything 5.0W and below to be too cool.
YMMV

Thanks. The charts and Ohms law calculator are actually very useful though if you're using a fixed voltage or RBA.
My using a spinner guide for new to VV people.
Set the spinner at the lowest voltage.
Screw on your device
Take a vape
If you like the quality of the vape stop here
if not begin loop
spin up the voltage a little bit
take a vape
if you like the quality of the vape exit the loop
if you get an unpleasant taste spin the voltage down one notch and exit loop
If not go to begin loop
Just keep twisting it up and vaping until the unpleasant taste then back down a bit
Most people like to vape at the highest voltage they can before the taste goes off
No mucking with numbers
