Getting more into RBAs: ohms, coils and confusion

[Vapourangutan]

Hello everyone,

Few months ago, I switched from the expensive coils of Aspire Cleito to my first RTA: Serpent SMM and I noticed how cheap I can vape and how much flavour I am getting from my new tank. Until now I've used some 0.4 Ohms Clapton Coils as advised from a very nice and helpful member on here. But now I feel like I would like to try more new stuff so some dumb questions emerged:
1.Can I use any kind of resistance for my coil for example in my Serpent SMM? Can I for example put a 0.6Ohms or a 0.2Ohms and as long as I adjust the wattage (0-80W as my mod can) it should be fine?
2.If yes, can I do this in all types of RBAs be it RTA or RDA?
3. In an RBA if it is a double-coil does this mean that my total resistance will be different from just one coil?

I know these may sound like silly question, but I can't stop thinking about it and it's better just to ask rather than waste money or do something wrong...
Thank you in advance! Happy vaping!

Yes
Yes
And doubling your coils will half the resistance.

What’s be said above is spot on and there are no silly questions how ever daft you think a question is when it come to vaping it wont be and plenty of helpful apes that will answer them if you don’t ask you will never know

Thank you for you fast answer! So just to make sure, if I have 2x0.4Ohms in a double coil system, the overall resistance will be 0.2Ohms? Am I right? Cheers!

Yup!

I feel so excited to try and learn about new things with such a nice and helpful community on here! Thank you!

'Ohms' is a measure of resistance ... if you remember that you'll be able to figure things out, resistance to the voltage.

If you have coils in parallel, the voltage can go through both at the same time, take the left path and the right path at the same time and pass through both coils, that's why it halves the resistance.

More wire will offer more resistance to the voltage (ie more wraps) and thinner wire will offer more resistance ,,,, because it's thinner, it's harder to get through, like a small tunnel is harder to crawl through than a big one... and the opposite is true for less wraps and fat wire, less resistance.

Call it what it is, 'resistance' and it will makes total sense. ... phrases often used like 'ohming out' won't help you to understand anything.

Just remember 'ohms' are the resistance of the wire to the voltage, and it's that resistance that makes the wire get hot, so less resistance needs more power (watts or volts on your mod) to get the wire hot.

If your mod is max 80watts then I'm guessing it's single battery.

That will need recharging a lot more often if you run a dual coil low-ohm set-up

It is an eLeaf iStick 80W

Makes much more sense now! Thank you! I should not have missed those physics classes from high school....
