Duel coil questian

[Leithan]

If i use duel coils will it split the resistance much like using twisted wire? Or is there a way to set it up so the resistance of the two coils is added together? Pics would help.

Sorry I can't help. I don't ever use dual coils. Just my personal preference. But hoping to bump so you can get the answer you need.

It is not like twisted wire. dual coils are 2 coils wired in parallel. Ohs law gets funky when resistors are run in parallel. To keep it simple, if you make 2 coils of the same resistance then your total resistance will be equal to half of one of the coils resistance. Example below

Coil 1= 1ohm
Coil 2= 1ohm
Total resistance= .5ohm

To get the resistance of you coils to compound you would have to wire them in series. Maybe it could be done but itd have to be a crazy pos neg connection setup on the atty. if you can figure a way to use only 1 negative connection and 1 positive connection and wrap both coils with one wire that would be series.

Thanks Varivapr thats kind of what i figured

There is no funkines, total resistance for an electric circuit in parallel: the inverse of the sum of the inverses

But, total = 1 / ((1/resistance1) + (1/resistance2) + ... (1/resistance n))

If your coils are the same resistance, or very close, just calculate as:
1/(n/Ohm)

If you are using just 2 coils:
.5*ohm.

N=number of coils
Ohm, resistance of the a single coil

So yeah you basically you cut the resistance in half for dual coils if you get each to be the same resistance

Still, knowing the parallel circuit formula is useful if you want to get funky with triple coils, etc

For series is just the sum of each, why don't you just add wraps? Each wrap is like added a tiny extra coil to a series

Hope this helps but without the Non resistance leg in the middle one could argue the two coils is actual one big stretched out coil with an exposed "Hot-Leg" in the middle witch will make your vape taste horrid unless the wick material touches that also.
Remember exposed resistance wire adds a nasty taste to your vape. Technically you have to have a space in the middle that's non resistive to make it an honest 2 coil in serial circuit.

I'm a lousy teacher but remember the space in the middle is NOT connected to anything. It's no more then the positive of one coil connecting to the negative of the other. "Tuning them [or matching] is a trick, they need to be the exact same resistance each then again the same goes for our parallel coils.
