Amount of "loops" in a coil

[DanJiblets]

So I'm lazy and use premade occ coils for the most part. I've finally started playing with my rba deck in the subtanks. I'm looking at the prewrapped ni200 coils on fasttech right now. It shows all the different resistances, but also shows the amount of loops. What exactly does the amount of loops mean, or affect? It goes from 8, 10, 12 loops, maybe even more. Not even ordering, just want to understand.

I would suggest you do a little studding in the RBA section so you can get a working knowledge of how to do it safely its not very complicated a little reading and youll be building your own set ups in no time. More loops means more surface but more amps drawn from your battery same with wire size.

What exactly does the amount of loops mean, or affect? .

Resistance is based on wire gauge and strand length. The wrap count is a side effect of producing a coil on a mandrel of 'X' size. In other words, two coils of identical resistance can have a differing wrap count if one is made on a 2mm mandrel, the other on a 3mm mandrel.
Disregarding current applied for a moment and just considering physical properties... an "optimal" coil is one that provides the desired resistance, surface area and... the physical properties of length and diameter to fit your atty - and make best use of your desired wicking product.

They're call "wraps" instead of loops

the longer the wire the more ohms you get.
A roll of wire has a number of 'ohms per inch'

The ID is the INTERNAL DIAMETER of the coil.
If you use bigger ID, you need less wraps to reach the same ohms.
Or thinking the other way: If you use bigger ID, same number of wraps , you get more ohms (because it's more wire).

7 wraps is popular. (I like ten; it's a metric thing)

Okay. I'm not gonna lie, your description lost me lol. That's why I just use the occs, it's guaranteed safe, quick and easy. I figured hey if i can just buy these prewrapped coils and some cotton it'd be way cheaper, and I wouldn't feel guilty ripping the cotton out and starting a new one for a different flavor. I'll do some research first thanks.

Actually you got the amp draw backwards. More resistance actually require less amps to hit the same wattage as a lower resistance coil. It takes more volts to get there but the amperage is lower. The caveat is, you might need more watts to heat a higher resistance but not necessarily..

This helped a little more, thank you. It looks like the coils with the rba deck are 6 wraps, so maybe that's around what I'd look into. Sorry I know I probably look like a dope, I have always just kept things simple. I've never even looked into this stuff as I've used occs, before that premade kanger dual coils

If you're happy with the pre-made coils, just keep in mind that they're much more expensive than buying the wire by itself and wrapping em. It's really not hard at all, and it'll have a nice payoff. I can spend 5 bucks for enough wire to last for a long long time.

I was looking at prewrapped coils and a lot of cotton for about $10 shipped. It'd still be dirt cheap and I wouldn't even have to wrap any wire, they're prewrapped. So I saw the resistance, great. But then I saw the number of wraps and was unsure. I didn't see how an 8 wrap coil could have .6 resistance, but another 8 wrap coil could have .9 resistance for instance. I only noticed the number of wraps like that for the ni200. The kanthal seemed pretty straight forward. I still only pay like $2 an occ and they last me a couple weeks, so no big deal. But those times I want to switch to a new flavor, it'd be nice to just throw a new prewrapped coil in the rba and some cotton and spend like a dime as opposed to the $2. The way I do it now, I either finish a bottle of juice off or wait until the coil taste like crap to make sure I get the most out of it.

you have to also look at the wire gauge (thickness)

Ni200 wire is much lower resistance than kanthal, almost an astronomical difference. A .6 ohm Ni 200 coil would be massive.... if you used a 2.5mm inner diameter coil it would be 50 wraps of 30 gauge wire. Not a typo.

1:
I remember rip tripper commenting about 7 wraps;
I think of that as being a minimum; I aim for 10 (round number)
that way it's more than 7 but less than too much (15....20)
2:
Your questions have been clear.
3: KISS; Keep It Simple Stupid will $save$ you dollars in this stuff especially when getting started; after that it's your wallet.
4: I survived on kanger single coils for a full year back in 2013/14 when I started

Thanks a lot for the help guys.

No problem! I didn't start rebuilding until my subtank occ decided to stop working and all I had was the rba. Best move I've made for vaping enjoyment. Pretty soon you'll be doing builds in 5 minutes.

Also just so you know ni200 wire is only meant for temp control devices so if you only own a vv/vw device DONT USE NI200 WIRE! Use kanthal a1. If you do own a temp control device then ignore what I said lol [emoji14]

I do, I have the evic-VT, thanks for the heads up. That's why I'm looking in the first place. Now with needing different coils it'd be easier and cheaper to just wrap my own. I just want to know what I'm doing before ordering anything.

One thing to keep in Mind about the Amount of Loops (or Wraps if you want to use that term) is that More Loops means a Longer Coil. And you can get to the Point where it is Hard to fit a Coil on a Deck.

Or like what I found when I went to do my 1st Rebuild on a Kanger OCC head, to Big to fit in the OCC Head.

I like stay around 7 Loops for my RTA's.

Any more and things start to get to be a Tight Fight. And much less than 5 and I don't get the Same Flavor that I do from 7 Loops.

Stick to regulated devices and prebuilt coils and go study up on ohm's law...safety first

These are the kanthal prewrapped ones I was looking at. They're about identical to the ones included in the subtank rba, without the spacing between each wrap. I'm sure I could easily open them up though.
