Oh thank you I appreciate that.
And I'm literally asking about the mod setup, not so much the safety I understand that I always need to have a ground and how to prevent shorting but how to apply ohms law to my mod for improvement is where I get stuck.
The safety aspect of a mod doesn't really consider whether you have a ground. It seems to me that without a ground (a path for current to flow to the negative terminal of your battery), it's as safe as it gets - no current can flow, and no potential for harm! The danger comes when you allow (knowingly or not) the battery to supply too much current.
What kind of mod and atomizer are you using?
Each part of ohm's law doesn't correspond to a physical part of your PV. Your coil/wick/atomizer determines the experience, and your battery determines your safety.
For a given coil, assuming your wicking can keep up, more wattage always means more vapor. With a VV/VW mod, you can simply crank up the voltage or wattage to achieve this.
On mechanical mod, you can only accomplish more wattage by lowering the overall resistance of the build.
But wattage is only a small piece of the puzzle. Airflow matters a great deal, wicking is of utmost importance, as well as how responsive your coils are. For example, given two one-ohm coils, one 28 gauge and one 24 gauge, there's far less metal to heat up in the 28 gauge. This means it will react more quickly, given 10 watts. On the other hand, it also has less surface area: less area to come into contact with liquid, and may well produce less vapor.
When I started rebuilding, I hoped to find some kind of "end all, be all" guide to how all the parameters affect your vape. Unfortunately, such a guide doesn't exist, to my knowledge. By hanging around ECF, you can learn a lot. And you'll learn even more by just trying different builds, and playing around.
Welcome aboard!
