What creates cartomizer resistance?

[spaceballsrules]

What part of the manufacturing process dictates the resistance of a cartomizer? Is it the thickness of the wire used to make the coil?

Also, I was wondering about single vs. dual coil as it relates to resistance. I have read that a 1.5 ohm dual coil is actually running at 3 ohm total.

Lastly, is there any difference between horizontal vs. vertical coils as it relates to resistance?

Thanks in advance.

I would really like to know the answer to this, as I have already looked high and low. Thanks

As far as I know resistance of a metal is dictated both by the type of metal and how much of it there is for electrons to go through. So, both thickness and number of coils (as well as type of wire used, but I don't know if this comes into play with e-cigs) would dictate the resistance.

Also, I was wondering about single vs. dual coil as it relates to resistance. I have read that a 1.5 ohm dual coil is actually running at 3 ohm total.

This might explain it for you: Dual Coil Cartomizers

Lastly, is there any difference between horizontal vs. vertical coils as it relates to resistance?

I don't think so. I think it just has to do with where the coil is located. Horizontal coil is going to have a coil at the bottom of the cartomizer. Vertical will have the coil running up through the filler.

The resistance comes from the nichrome wire used in the coil(s) of a cartomizer. A given size wire will have so many ohms per inch of resistance. More coils = longer wire = more resistance for a given size of wire used.

A 1.5 ohm dual coil actually has two 3 ohm coils, in parallel. Each coil dissipates the full battery voltage, draws the amps needed for it, so the total current coming out of the battery is twice that needed for just one of the coils. A 1.6 ohm DC has two 3.2 ohm coils in parallel. A 2 ohm DC has two 4 ohm coils.

For a more technical explanation, see: Series and parallel circuits - Wikipedia, the free encyclopedia

Horizontal vs. vertical doesn't inherently do anything relative to resistance, it's just physical orientation of the coils. Where it comes into play is in the total package design, how well the coil heat is being used to vaporize the eliquid, how fast things will dry out, ...

Aha! I thought that DC cartos had 2 coils running in a series, and not a parallel circuit. That clears up a lot. Thanks!

Now I understand why DC cartos stress the battery out so much more. MOAR POWER!!

... MOAR POWER!!

Indeed!

Yup! Lots of vapor but little heat... It's like vaping two 3.0 Ω cartomizers at the same time....
