Ohm x voltage = What?

[robo2000]

I know voltage increase creates more vapor, but what exactly is the Ohms part of the equation doing for us that use a variable voltage unit?

If someone could point me in the right direction, it would be a great help. I mean there has to be a thread or two already dedicated to this topic. I just haven't been able to find it yet.

Ok I found some now how do I kill this thread?

Voltage/wattage/amperage do not increase vapor, directly. Temperature of the coil vs. area of the coil vs. amount of fluid at the coil does. Ohm's law will explain resistance to you, and its' interplay with the rest. That said, none of it accounts for temperature of the coil (not directly, that is) - so keep that in mind. The right temperature over the maximum amount of fluid will have the best vapor/flavor production. You have to keep this in mind when striving for the optimal vape. Electrical theory gives you the science, but you have to find the proper application of that science to make it work well.

Technically, wattage does directly relate to heat output....1 watt for a period of one second = 1 joule. But then there are the other factor like how much heat is transferred to the juice, how much is transferred to the air, how much us transferred to the wick, volume and density of the fresh air supply, etc, etc...

Calculating watts is by far the easiest method of roughly measuring a vape. More watts equals more heat, equals a hotter vape. The other factors are usually proportional so it's pretty much impossible to increase the wattage and get a cooler vape from the same atty without drastically changing your draw.

Ohm's law is used to calculate the wattage (among other things) and there are 3 different formulas to use depending on which factors you have.

V²/R

V*I

I²*R



or Layman's terms



Volts² / Ohms

Volts X Amps

Amps² X Ohms
