So confused with my Dual Coild RDA - Ohm problems...

[Rypp]

Hi guys,

I decided to try out my first RDA, I got the smok Scar and it's a real nice bit of kit. I was vaping the stock coils for about a week and wanted to change flavour so thought I would try making my first coils.

I watched a few Youtube videos and gave it a go. I used Kanthal A1 Resistance Wire 0.30mm and checked the ohms on my Vamo, I had so many different ranges from 0.1, 0.5, 0.3.. I tried with 4 wraps, and then up to 8 wraps. When I tried it with 1 coil and (i think) about 5 wraps I had a 1.0 reading, but when I added the second coil it dropped again, I want to hit between 1.5 and 2.0

I think I remember hearing that double the wraps = half the ohms or something, but that would mean a lot of wraps and the stock ones only had 4? Maybe it's the wrong resistance wire?

I am a complete novice when it comes to RDA's, and probably have this totally wrong but I am keen to learn. I wasted all my wick trying to figure this out so would value your input.

I apologise in advance for asking a question which has no doubt been covered a million times.... but it seemed no matter the amount of wraps it made little to know difference.


Thanks

This might help you:

Anyway a longer coil wire = more resistance
More coils in parallel = less resistance

Thanks for the link, I'll give that a look.

*Edit - oh wow, according to that link I was way off with my number of coils, and wire length.

When you run dual coils, the resistance is halved. i.e. running @ 2 ohms, you would need 2 4 ohm coils.
