A coil question-serial dual coils.

[conanthewarrior]

My brain is hurting trying to work out what you mean.
To me two coils with or without a cut in the wire are more or less the same.
The preasure is fixed (on a mech at least by the battery voltage)
Regulated devices I do not use so have no idea.

I am sorry, it is very confusing to myself what I am trying to portray.

We know that one single length of wire, without a cut will have higher resistance due to wire length, while a piece of wire, the same length, but cut, results in around half the resistance.

I should add-my original question is answered though-this is just an after thought.

Here is an image of the build I am talking about. https://www.fasttech.com/forums/1594300/t/1171824/serial-dual-coil-build/1

I did mean to add-I understand we are talking tiny particles, that take the path of least resistance-answering WHY the splice is noticed, but I was confused when you stated that the single, longer piece of wire will be the path they choose as that will have a higher resistance than dual coils with a splice, as we know that is halved?

I am glad I have the answer from you though on HOW the splice is noticed. Thank you for that.

In a 3 post sleeper build ie 2 coils made from one piece of wire that is secured on a single positive and 2 negatives the resistance will be slightly lower than 2 separate coils in the same 3 post atty because of the above. If you build 2 coils out of a single piece of wire and connect one end to a positive and the other to a negative like in a velocity deck resistance will increase because there is more wire to travel through. Does that make any sense?

The cut is, in this case, irrelevant, its the fact that the ctr pin sits between them so the coils sit in parallel, I've drawn it out below, but I warn you, years of CAD have rendered my sketches appalling!

That is perfect. I completely understand now.

The build I saw was on a RDA with two posts-one positive, one negative, and I understand that on a 3 post atty, due to the central positive pin and connection at two negatives, it causes the effect.

I finally understand serial dual coils.

This thread was a bit hard-partly due to me not being able to talk the way I used to, and having to use very long ways of explaining things to get my point across.

Thank you so much. All is understood now.

OK, I finally got it thanks to yours and @drlnhs explanations.

It was a bit confusing, but I am glad we all got there in the end.

Awesome. Thanks my friend great thread
