If you are related to the world of vaping , either because you are starting out or because you have been in this for a while, surely you have heard something called resistors or with their name in English "coils", these are always accompanied by a number like the following 1.2 ohm, 0.8ohm, among others, this refers specifically to the ohmage of the resistance. Next we will explain this term a little better.
First of all, let's define what we mean when we talk about ohms. An ohm is a unit that measures resistance. If we talk about vaping, would be the difficulty encountered by electric current to complete a circuit. The lower the ohmage of a resistor, the less opposition it makes to the flow of electric current, so it needs more power and more time to heat up.
Usually, the commercial resistors themselves usually indicate the power range in which they can be used. This range is usually given by two points, the ohmage that the resistor has and the material it is made of. When the vaping , the ohmage of the resistors used to be between 1.5 and 3ohm. Then came the mods and with them the sub-ohm resistances, resistances that have an ohmage of less than 1.0ohm and that allow a greater vapor by requiring more power and, therefore, the concentration of nicotine in the liquids must be reduced to avoid an excess. of nicotine absorption, plus a throat hit so strong it's annoying.
There are two main categories of vapers:
1. Those who prefer mouth-lung puffs (MTL), more similar to a traditional cigarette puff and which are achieved with standard resistances of more than 1.0ohm in addition to powers normally less than 20W.
2. On the other hand, those who prefer direct lung puffs (popularly known as DL or less commonly DTL) that are achieved with sub-ohm resistances and with powers greater than 20W.
Today, Pod-type devices, discrete electronic cigarettes, with low powers and with cartridges that normally have resistances greater than 1.0ohm, have become fashionable again.
With these two definitions we hope that you are a little clearer about what type of vaping you prefer and what is the appropriate resistance for each of them. Remember that you can also get better advice before making any purchase to make sure you do it correctly.
