Try this link Ohm's law - Wikipedia, the free encyclopedia

What it means is that a 1.5 ohm resistance will be hotter with less voltage . Good for someone on an ego battery which is 3.4 volts fresh off the battery . 2.5 ohm's will be cooler and produce less vapor but your battery will last longer before it needs a charge . Less resistance = more current . If your going to hit it with more volts from a VV mod then you probably will want the higher resistance carto . If you want more current you either lower the resistance or raise the voltage . If you use the 1.5 ohm carto with higher voltage you could burn it out so you would need to lower the voltage .

An ohm is the units for resistance. Attys/cartos are often sold with the ohms stated. Basically the lower the ohms the warmer the vape and the more power will be drawn from the battery.

Not sure how well 10440s will work with the 1.5 ohm dual coil cartos. May want to wait for one of the more electrically talented vapers to stop by. You say your PV is 'variable', does that mean variable voltage?

.... Did a quick search for the Little Sister (only VV commercial mod I'm aware of using 10440s) and dual coil cartos and came up with this http://www.e-cigarette-forum.com/fo...-vv-mods-fire-them-correctly.html#post3218748

Think of a light bulb. The higher the watts, the brighter the light.

Watts = Volts / (Volts / Resistance (Ohms))

the higher the volts or lower the resistance, the higher the watts will be.

A 3.0 ohm carto or atty @ 4 volts is 5.3 watts.
A 2.5 ohm carto or atty @ 4 volts is 6.4 watts.
A 2.0 ohm carto or atty @ 4 volts is 8 watts.
A 1.5 ohm carto or atty @ 4 volts is 10.6 watts.
A 3.0 ohm @ 5 volts is 8.3 watts.
A 2.5 ohm @ 5 volts is 10 watts.
A 2.0 ohm @ 5 volts is 12.5 watts.
A 1.5 ohm @ 5 volts is 16.6 watts.
A 3.0 ohm carto or atty @ 6 volts is 12 watts.
A 2.5 ohm @ 6 volts is 14.4 watts.

Some people run 1.5 ohm duals @ 6 volts. 24 watts!

A dual coil 1.5 ohm on a RIVA is about 10 watts. I like my 1.5 duals around 4.4 volts.

I might be completely wrong.

I'm thinking when ordering DUAL coil cartos you can't use the same reasoning because there are 2 coils and if you order a 2.5 it's not like ordering a regular boge 2.5. If you go to the Clouds of Vapor website and read the description of the dual coil 1.6 ohm it kind of makes sense. Says "two 3.2 ohm coils give total resistance of 1.6" So the label will say 1.5 or 1.6 ohm. These electrical formulas make me want to smoke, glad there are no analogs in the house.
