Im a rba noob and looking to get better at wrapping my own coils and understanding how the law of ohms works, and how amps plays a role. Being that I couldn't find any threads thru the iffy ecf search engine, I started a thread. basically I have no idea what battery amperage and voltage has anything to do with resistance/ohms. link me to other threads or explain yourself.

Ohm's Law Calculator
Basically...
If you wrap a 1.5ohm coil, and have a mechanical mod, and the batteries are fully charged to 4.2 volts, then it would be 2.8amps
You just have to check and see the batteries c rating, and make sure it is safe.
However, just because a battery is rated at 20amps doesnt necessarily mean you should be running them that way.

So, with my voltage at 4.2, resistance at .6. the calc tells me 7 amps, and about 30 watts. what does that info tell me? I need a battery with a c rating of atleast 7 amps? and itll be running at 30 watts???
You should lookin to micro coils.No need for .6 ohm coils and will be much safer since you are new to RBA/RDAs .
Plus they are super easy to wrap .

Those numbers were purely hypothetically but you've sparked my interest.
Does a 1.2 ohm micro coil match the responsiveness of a sub ohm normal coil?
But I still need to understand those hypothetical numbers.
Hit up the micro coil thread either way .The guys in there can give you all the info you need .Hope this helps ! 
If you have a smart phone download the ohms law app. On a regulated device your really going have a lot of leeway on your coils since you can adjust the device for taste. If your trying to find the most your device can put out since they all have an amp limit and a watt limit the app can help you quickly find that. On a mech mod the app can tell you what ohms to wrap for your preferred power at the coil. Here's a link to help with the volts/watts and how they relate to your vape http:/..................../wordpress/volts-vs-ohms/ there is also a link to a chart on this page too. It's all personal preference as long as your not burning your juice or pulling too much from your batteries.
If you don't have one already get an ohm meter. You'll need this to check ohms and to check for shorts. Once you make a few, on silica based RBA anyway, you will know if your going to short or not based on where your wires are most of the time. On mesh wick devices there are more ways to get shorts.
Let everyone know what RBAs you have or are going to be getting and what devices you'll be using them with and everyone here can give you more specific advice.
Once your infected with the "I can make this better" virus pretty much everything becomes an RBA If your already infected or you become infected get your wire off ebay. You can get 100ft spools of wire for around the same amount of $ that 6-8ft costs at online stores or B/M shops. Wicking material is more a personal preference. I've been very happy with silica and SS mesh but I also like cotton. Other people swear by high temp sleaving, SS wire rope, hemp, bamboo, ceramic hell even air stones for aquarium filters the sky really is the limit. I've experimented with a lot of this stuff but I always go back to the silica or SS mesh. It's just easy to use and gives a great vape without a lot of fuss.
Post up what your working with and I'm sure some of the experts will chime in and get you happy with your kit in no time, I've been taking their advice for a while way before I signed up to post on here.

Yes, you would. I would stick with aw or efest imr batteries. I run around .7ohms on all my genesis attys and have never had a problem out of either brand. I have used them to mess with some .2 and .3 coils, but to be honest, i can get more vapor and better flavor out of a .7ohm coil. With the micro coils though, it is a bit slower heating up. but we're talking nano seconds, hardly noticeable if you do it right.
Edit:
Also, I would like to know what you're using, mech mod or what. And what RBA/RDA?
Also, this guy may not know it, but I learned a lot from his posts when i first came into rbas.. and i just watch a video of his on micro coils...

Im using vamo v3, with aga t2. so im restricted to 1.3+ ohms, was considering getting mech for subohms because I want the responsive heat but if microcoils provide a hardly noticeable difference ill probably stick with my vamo and just stay around 1.3 with micro coil. im looking into how to wrap them now, looks simple. so awimr/ efest imr for sub ohms and what for 1.3 ohm micro coil?
silica gives me a strange taste, and I don't like using cotton because low combustion temp. could I use vertical SS mesh with microcoil?
Def agree with dhughey, .7 on a genny on a mech is a great vape. Keep in mine that air hole size is also not only a very personal thing but plays a huge factor in flavor and vapor production. Too large and flavor goes down but vapor goes up too small and you'll feel like your drinking a milkshake though a straw. I like 1/16 inch to 3/32 inch for the air hole, lately 1/16, this on genesis attys. On gennys I like to inhale direct to the lungs so the draw needs to be pretty open. 3/32 give more vapor and a better draw but 1/16 give me better flavor and the clouds are still pretty large.
The micro coil thread got me on my newest experiment that actually turned out surprisingly good. I have a 2ohm coil on an RSST sitting on the provari. The response time is pretty slow but it's not a problem to cook it a sec before taking a draw. To my surprise the vape is very comparable to the .7 on the same atty sitting on a natural with the contacts sanded. I was not expecting that at all. It's so close performance that I'm more than happy with it and now I can get that same vape until the battery light blinks. The micro coil thread is pretty big but there is a lot of golden nuggets in there. I can't really call my set up a micro because I have a huge solid wick in there to hold enough juice for my long draws but the principals in that thread gave me one of most enjoyable vapes I've ever had on a regulated device. Of course when charged batteries are near the .7 on a mech still wins. RBA are more about the experimenting for me, I can get great vape on a lot of things but a 2ohm coil on a genny giving a great vape was very eye opening.

I use the aw and efest for everything. I have a v2 vamo that i use sometimes, but honestly since i got my nemesis and a couple other mech mods.. i haven't really used it that much. I actually got better after looking at these pics from another member.

But if you want a mech check vaporjoes, there are some good affordable models out there, and clones.
Edit: and if you have any future questions.. feel free to pm me.

SS mech and micro (ish) coil on the vamo will be great, thats pretty much how mine is just higher ohms on a provari. I'm running at 5.4 volts wich is all the provari will handle with the 3.5 amp limit and the 15 watt limit. I think the vamo is the same watt wise but if I remember right your amp limit is higher than mine so a 1.3 coil can give you more head room than I can get.
Wow, i was just about to say something about the airholes... I agree with you, very personal experience and one you have to try to know what you like. I would just start out small and move up from there.
Personally I have a zen standard with 2 top caps. One is 1/16 and the other is 5/64. I use the smaller hole with some liquids that don't have a strong flavor, such as agent oragne. However, something like pluid or grenada, and you can open your airhole as large as you want for super vapor and not lose the flavor.
On a nimbus i actually have a (dual hole) 3/32 which is pretty large, but i run dual coils at around .5ohm overall and its one that is home use only. I really cant be blowing clouds in my office.

Yeah duals at .5 is def home use only, people might think you have a car fire at a stop light 
The guy I see most at the shop I go to had his nimbus set up similar to yours. I've been vaping 6mg juice for a few weeks at this point, his was loaded with 18.....it hit me pretty damn hard and I didn't need a vape for a while after that
