Let's look at how a set up works with our scales
we have amps, watts, volts and ohms.
You only control 2 of them at a time the other two fall into place.
First off let's look at watts, the higher the wattage the more vapor is produced and wattage has a direct correlation to voltage and amp draw required ( as you raise wattage, voltage output goes up and the higher the amprage needed to safely maintain your build)
Next let's look at voltage and ohms together voltage is the work being done by running electricity through your atomizer measured in ohms. As your voltage goes up you risk burning your
coils and
juice as you lower your ohms your voltage goes down so as you lower your ohms you can raise your wattage to produce more vapor but the required amps is also raised.
Now remember how I said you can only control 2 variables at a time? 1 is ohms no matter your mod you control the resistance of your atomizer. The higher the resistance the less power needed.
Now the second variable you set is dependent on your mod. Your regulated mods are either variable voltage or variable wattage. however your standard mechanical mod uses amps to complete the equations which is why it can be dangerous but that's another discussion... and is not my specialty.... actually no mech experiance
