I'm new to vaping knowledge wise and need to A. Get a grip on the Ohms law (any references?) And B. I enjoy vaping in general to play with clouds. I have a Nemesis with a 18650 and use max VG liquid as it is. I have a troll tip with adjustable air intake, three diagonal lines on each side with a walk i can slide over them if i want. I was wondering what exactly causes something to produce a higher or lower amount of clouds, i already have it so i get quite a lot but id like more. I dont kniw my current Ohm. Stock wire (so im not sure) but 6 wrap. Dual. Any help is appreciated. Or general information to help me know more about what im getting into.

Hello and welcome to the forum @RD Disturbed. Glad to have you here!
#1 -- get yourself an ohm reader
#2 -- know the CDR of your batteries
When considering how low you can build you need to give yourself some headroom. I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 30A battery, that would be 15A. This Ohm's Law Calculator tells me that a .28 ohm build is as low as I would want to use.
The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, a 20A battery may only be a 10A battery.
Since you are new to mech mods and/or rebuildables I highly recommend you spend some time with @Baditude & @Mooch (two of our resident battery/safety experts) and visit their blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.
Here are links to some of Mooch's blogs:
* No matter what is printed on the battery wrapper: There are no 18650 batteries with a genuine rating over 30A!
* Links to all his battery tests to date: List of My Battery Tests | Mooch's Blog
* Picking a Safe Battery to Vape With: Table of 18650 Battery Safety Grades | Mooch's Blog
Baditude's Blog - Table of Contents: The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:
BATTERIES
Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.
OHM'S LAW
Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.
Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics
* Battery Junction**

+1 to @Susan~S . THe very first thing you need is an ohmmeter. I like the Nemesis myself, I have 4 or 5 of them in various finishes and I use them all the time. But they are only a one-battery tube mod and it isn't too safe to coil them below about .4-.5 Ohms, depending on what batteries you are using. If you really want big vape on low builds, you're going to need at least a two battery parallel box, which can be safely coiled down to .2 or so-- again, depending on good batteries-- or far better still a regulated box mod, something like a Snow Wolf 200W or a Segelei 150 W. You have come to the right place for your info. Susan has already linked you to the reading you need to do to get you started. @Baditude and @Mooch are two of our resident battery guru and they know whereof they speak. I will personally recommend Sony VTC4s in that Nemi-- that's what I use in mine-- and I try to keep my builds above .5. On thing Susan did not link you is a coil calculator. You can find a good one, called Steam Engine, here. That will help you decide what size wire and mandrel and how many wraps you want to make your target resistance. Once you read all that stuff you're sure to have a number of questions. You'll find a great number of helpful people around here to help you answer them, so just make us a post and ask.
