Wow Im new as well and you guys make it sound so complicated voltage watts etc. I have 3 ego c passthrough batteries and 4 vision clearomizers thats it guess I will learn more stuff as I go Lots of info on here Today is day 15 for me and so far I have had no problems Congrats to all that are new to vaping Have a great day fellow vapers
I think there's a very basic amount of information about volts, ohms, and watts that is so crucial to a satisfying vaping experience - and therefore, crucial for success in the War on Smoking - that's it's worth taking about three minutes out of your life to get a handle on.
I think it will also save a lot of wasted and frustrating time spent wondering why you're not getting a satisfactory vape, or trying to decide what resistance of coil or coils you should be using.
It really is not very complicated.
The watts (heat) at the coil or coils is a function of the volts flowing through the resistance wire that the coil is made of.
Having a variable voltage device/PV/APV/battery lets you control the amount of watts (heat) of the coil or coils, allowing you to tailor your vape for a variety of flavors, resistances, or moods.
It can be expressed with the only formula you need ever be exposed to, and that you don't even need to memorize, although it's pretty simple:
Volts times volts divided by resistance (in ohms) equals watts (heat), or
V x V / R (sometimes expressed as "I") = W.
So;
X volts with a lower resistance coil = more heat (more watts).
X volts with a higher resistance coil = less heat (fewer watts).
This is why you wouldn't want to use a 3 ohm single coil with your eGo-C (constant voltage) battery.
3.4 volts x 3.4 volts / 3 ohms = 3.85 watts. Kinda "cool".
A 2.0 ohm single coil would be better.
3.4 volts x 3.4 volts / 2 ohms = 5.78 watts. Probably a better vape.
If you had a variable voltage eGo-class battery, you could have a much wider and more adjustable range of temperatures at the coil. With a Twist, you could plug in a voltage of anywhere between 3.2 and 4.8 with either a 2.0 or 3.0 ohm single coil and get just about any reasonable wattage you'd be likely to desire, regardless of the flavor or PG/VG ratio of the juice, or variance of resistances of coils from their "nominal" rating (a "2.0" might actually be a 1.8, or a 2.2, for example).
Variable voltage just lets you have a better chance of having the coil at a temperature that gives you a vape that you'll like, and that will get and keep you off of cigarettes; in other words, "fulfill my agenda".
