In this post I'll attempt to explain the relationship of Current(amperes) to vaping when choosing a VV mod.
A little Physics before we begin. Lets look at the fundamental equations that affects vaping
Ohm's Law: I(current) = V(voltage) / R(resistance)
Joule's Law: P(watts) = I*V
This 2 equations will determine whether your PV is able to support the atty/carto(referred to as atty hereafter) you choose to use.
Currently, there are many types of attys available but I'll classify them into 2 type. Single coil & multi coil. Top, bottom, vertical or horizontal coil does not affect the power consumption so I'll not talk about it.
Single coils are very straight forward as most generic ones are 1.8Ohms. Pop it in and you are good to go. They are fuss free IMO.
However the game changes when you use a multi coil(MC) atty. The labelled resistance of a MC atty, is actually the average resistance of all the coils inside. To get the actual resistance of each coil would mean taking your atty apart but we wouldn't want that so we shall assume that they are of equal resistance. I'll illustrate in the scenario below.
We have a dual coil atty rated at 1.5Ohms and to find out what is the resistance on each coil, we use
1/[(1/1.5)/2) and we get 3Ohms. So applying Ohm's law when vaping at generic 3.7V PV we have 1.23A across each coil. Multiply that by 2 for Dual coils we get 2.46A and apply Joule's Law we're vaping at 9.12W which is a little about the "sweet" zone of 7-9watts.
You may think,"Wow! Not bad. Close enough. 9watts for 3.7V." Think again. You are actually getting lesser heat from each coil due to high resistance because each coil now is only producing roughly 4.5watts of energy not to mention your batteries actually drain faster.
So what happens if you want to increase the voltage on a VV mod?
Simple. Just crank it up. However, you will notice on single battery VV mods, no matter how high you crank it up, it will drop back to around 3.7V max 4V. Why is that so? This is simply because single battery VV mods are design to use a DC-DC boost converter commonly known as booster. However due to limitations in its design OTS boosters suitable for vaping are mostly limited to 2.5A. So the mod is designed to limit the current output by lowering the voltage to a more sustainable level.
Back to the DC atty we were talking about. For 3 Ohm per coil, you could have gone up to at least 5V and not have burning taste but u're stuck at 3.7V. Suxx ba||s right?
So the next time you're shopping for a VV mod, look out for something that can give you at least 5A to fully enjoy you multi-coil atty.
Till next time.... Have a nice day.
