Not sure what cartomizer to use or replace with?
Ohm’s? and voltage?? Here’s a little help.
Ohm’s law, (Voltage x Voltage) / Resistance (ohms) = Power (watts)
Knowing this formula is crucial to understanding what variable voltage is all about, and helps gain a better understanding of how the different combinations of vaping equipment perform relative to each other.
Here’s a look at a few examples.
Most standard 510 atomizers have a resistance of 2.5 ohms. Mass produced PV’s such as the 510 and the eGo run around 3.2v. Using Ohm’s law, we can calculate the power output for this configuration.
(3.2v x 3.2v) / 2.5 ohms = 4.096 watts
If you use a standard 510 atomizer, but instead step up to a 3.7v device our power output increases.
(3.7v x 3.7v) / 2.5 ohms = 5.476 watts
If you use a non-standard atomizer @ 3ohms, but instead step up to a variable voltage 5.5v device our power output increases.
(5.5v x 5.5v) / 3 ohms = 10.083 watts
Note: higher resistance (higher ohms) last longer than lower resistance. It all depends on the voltages of the power unit.
