How many wraps and what size drill bit to get around 2.5ohms with 30g?

[Crexture]

I had to get 30g Kanthal with my IGO-W6 because they were out of other sizes.
My mod won't run anything under 1.3ohms so I need to know how many wraps on what size drill bit will get about 2.5 or more ohms for a dual coil build?
Thanks!

Use this link -- Steam Engine | free vaping calculators -- it's got a coil building section that I could not build coils without, you can customize your coils to suit whatever you like.

What's the difference between a parallel and serial coil build?
I can't find anything on it???

You need 14 wraps around a 1/16 drill bit to get 2.5 ohms.

a parallel is a type of dual coil build where you use one piece of wire only (say if you have not much room in your centre post) instead of two. Google Rip Trippers to see what i mean.

Dual coils are technically in parallel electrically speaking anyway, and that's why if you make 2 x 5Ω coils and fit them, your final result will be halved and you will get a reading of 2.5Ω if you measure your atty.

A series coil is like a single coil.

I appreciate the idea of shared diameters for having a common language. That being said I just use a micro screwdriver to wrap on and an ohm meter. May take you a couple builds with whatever you choose to use. If you need more ohms add a few coils less ohms a few coils less.
On a dual coil build you are halfing your ohms. That would be two 5 ohm coils to hit your 2.5. Figure out a single 5 ohm coil and then make a second one. Anyway don't know if what I said will help you.

That confuses me.
So if I built two separate coils and hooked them up in my IGO-W6 with each coil being (for example) 5ohms, it'll come out to be 2.5ohms?

I need about 1.5-1.4ohms in the end with the full build.

Oops assumed with his/her types of questions he/she had meant dual. Good point.

For dual that would be two single coils at 3.0 ohms or two single coils at 2.8 ohms

You had better read something like this:
Series and parallel circuits - Wikipedia, the free encyclopedia

You are working well within reasonable limits and i'm not worried about that, but you need an understanding of this stuff.

And this is the parallel coil i mean.

Be safe.

Thank you! This is what I needed.
I knew about parallel and series circuits
But I didn't realize that a parallel build was two wires in one positive and one negative post together.
