Coil Build vs Coil Build. What are the differences?? HALP!!

[ellupodilangelo]

Hey guys & gals. So I have a question and i hope some of you coil building savants can help me out with this. I always used the standard coil wrapped around a 3/32 drill bit and they were great. However I just got into building twisted coils and clapton coils and I have found that I enjoy the vapor from these builds MUCH more. For me... they produce a denser vape and depending on the atty a much more flavorful vape as well.

I've noticed that the ramp-up time is slightly longer which is okay with me... I feel a gradual ramp-up time will prolong the life of your wick as it gives it more time to actually wick as opposed to coils that go full heat in an instant. I get less harsh hits from a gradually ramp up than i do from faster ramp up times.

I know that the main reason to twist a coil is to cover more surface area on the coil and the clapton coil does this as well. What I want to know is how does the twisted and clapton coil effect resistance?

The reason i want to know this is because i want to be able to hit my target resistances when i build a coil and not just build something and then just live with whatever resistance comes out, or simply rely on what i see on videos.

Thank you all

If you have a multimeter you can test the resistance of the wire you just twisted up. Then knowing the length you need to get the ohms you want you just use that length of wire to wind your coil. I imagine it's difficult to just give numbers because depending on how tightly you twisted your wires (thus how much wire is actually used) can greatly effect its overall resistance.

Just be sure to note the internal resistance of the meter by touching the leads together and subtract this from the reading you get when measuring the resistance of the wire.

A twisted coil is nothing more than two strands of resistance wire in parallel. If you knew exactly how long each strand was, and its resistance, the coil would have half the resistance (and if you had a dual twisted, 1/4 of the resistance of a single strand, etc).

A clapton is also (if you're just wrapping one wire around another) two piece of resistance wire in parallel, but both pieces would probably have wildly different resistances, say R and S. Then the resistance of the clapton coil would be RS/(R+S).

I imagine it's kind of hard to actually wrap these knowing the specific lengths of each strand of wire involved (hence, each strands total resistance), but you could probably come up with a decent ballpark.

Like some have said, you can look at it with running the strands in parallel thus lowering the resistance. Or think of it as running thicker gauge wire which has less resistance. If you are already making clapton and twisted wire yourself, then hopefully you make it 2-3 feet at a time, thus you have plenty to play with, experience building coils with tell you how many wraps will get you close to your target ohms you are shooting for.

There is a twisted option on Steam Engine | free vaping calculators. When selecting the Material (kanthal, Nickel, etc), the dropdown window next to it, you can select round/twisted/parallel, window is called profile. Read the words there for how twisted it is (twist pitch) and number of strands.
