LR (low resistance) atomizer confusion

[JohnnySokko]

Hello.

I'm extremely confused about LR (low resistance) atomizers.

I know what LR atomizers are, what they do, and what they're used for, but I'm confused about why they're described as being "low resistance" when, in actuality, they should really be called high resistance.

A LR atomizer produces a stronger throat hit and more vapor because it burns hotter — but it burns hotter because it has a higher resistance, not a lower resistance.

The more resistance that a wire has, the hotter it becomes, and the lower the resistance, the cooler the wire is. So it seems that everyone has it backwards, i.e., people are calling atomizers that burn cooler "higher resistance," and they're calling atomizers that burn hotter "low resistance." That's totally backwards, though.

What's going on with the mixed-up terminology?

LR attys (2.0 ohm and lower) run hotter ( watts) than higher ohm attys. Lets look at Ohms law:

E²/R=W ( E = volts, R= ohms, W= watts)

Lets take a standard 3.7 volt battery with a 1.5 ohm atty:

3.7²/1.5= 9.13 watts

Lets look at a standard 3.7 volt battery with a 2.4 ohm atty:

3.7²/ 2.4= 5.7 watts

As you can see the lower ohm atty produces more watts ( heat)

Yes, that's correct. As you said, " [a] lower-ohm atty produces more watts (heat)."

However, a lower-ohm atty produces more heat because its resistance is higher, not lower. So shouldn't they be properly referred to as low-ohm atomizers instead of "low-resistance" atomizers?

People seem to be confusing ohms with resistance and have the nomenclature all mixed up.

I think you may be confused:

Ohm is the measure of resistance in a circuit to the flow of an electric current. The greater the ohm value the more difficult it is for current to flow through a given circuit. Conversely, a low ohm value represents a low resistance and the easy flow of current through a circuit.
