I need help with resistance and coils.

Hello there everyone! I never did a bulid before and i really don't understand what is the resistance on build coils and why should i know them and what they mean, and can i read the resistance from the mod or i have to get a coils master and does resistance determine what wattage i vape on? Ohh and I'm going to use the RBA coil that came with my big baby beast and ill use it as an RTA for my first time building and ill be using the cks icon 200 mod with the tank. Thanks in advance for your help!

The resistance aka ohms of a coil in simple terms is how easy power flows threw the coil.

It's not as simple as saying at this ohms you need about this much watts to run the coil tho. I can build 2 totally different coils that have just about the same ohm reading and they will require two way different watt settings to run each of them. It's based all on the size of wire and amount of wire in the coil.

Someone else might have an idea of what comes with the RBA section but I really don't have any idea.

Myself I have the pro version of the Vape Tool app on Android to help with calculations when building my own coils. Takes all the extra math out of figuring things out for myself. The base version works fine for building it just doesn't give an recommended watts range for coils like the pro does.

But why do i need to know how much power runs threw the coils when i don't have a mechanical mode?

Why does a mechanic need to know how much an engine puts out before putting it into a car?

There are many YouTube's that explains Ohms Law, you need to watch them before attempting to build.

You need to know what kind of current drain is being put on your battery AND the limits of said battery.

After battery sag (the internal voltage of the cell will sag when in use, the more it's pushed, the harder it sags. Anything over 100W on a single 18650 is going to push you down to around 3V, even fully charged at 4.2V.) and also voltage drop which is voltage lost in transit due to the mod itself.

Steam engine is one tool of many, ohm's law is a full equation and I believe you should be forced to learn it if you're going to build anything, the batteries you put in your mods aren't toys. They CAN cause harm if pushed hard enough and the last thing we need is another 'exploding mod' news story.

The thicker the wire (AKA the more surface area), the less wraps, the lower the resistance. We use resistance wire as when current flows through it, the resistance causes it to heat. The more power, the more heat. So MORE wraps and thinner wires would yield a higher resistance.

When you're building on an unregulated mod you need to take several variables into account. If you want MORE power, thicker wires or specialty wire (twisted, clapton, staple, etc.) are a good choice. You can also parallel wire on your bit when wrapping to cut your resistance down by around 50%.

Also, DON'T use shit batteries. If your battery isn't made by LG, Sony, Panasonic or Samsung (if an 18650) it's likely a rewrapped B/C-bin cell with exaggerated amp limits. The HIGHEST continuous rating on ANY battery 18650 wise is around 30A. The LG HG2 is the best, having a cont. rating of around 33A.

Most batteries in the 18650 range have a rating of 15-20A continuous, 30-40A pulse. Keep that in mind.

You dont really....... but your regulated mod does have limitations. It probably has a minimum and maximum ohm rate it can safely use. And a range within that at which it can provide full power.

So you do need to know how much power your mod is going to draw from your batteries to produce the performance from the coil.

Thanks for the advice! But im having a problem.. I used my RBA coil that came with my big baby beast and i wicked it and i taste cotton and the flavor isn't good enough.. What can i do? Sorry I'm new to this stuff :)

Most RTA'S require you to use less wick to get them to work right. But too little wick can cause leaking issues also. It'll take time and practice with wicking each RTA you have till you figure the tricks to each tank.

I may be asking this in the wrong place but Id like to know the difference in Niche-chrome 80 and N I 200, both 24 guage if anyone knows. If anyone knows, I would be thankful for this information.
