That is my fist sticky on my favorites bar so I can just pull it up all the time. I could not build a coil for weeks without it. Now I can build my set coils but if I want to change from 28ga to 30ga or the resistance, I do go to this chart all the time. Thank you for posting it for me. I just seem to have a big problem with how all the numbers work together.
So, the sub ohm coil is the bigger hose in the equation? I keep thinking that 28ga needs less coils to get to x ohms and it is the opposite, I think. Thus, the trusty Ohms Calculator.
See, DH for 22 years has been telling me I would get lost in a paper bag. lol You should have seen his face the first time I broke down my r91 and built and wicked a coil. It was priceless!
But I can do our taxes, pay the bills and hunt down the sales. Research how to fix a wood floor (with help from a friend), etc. Go figure. I guess we all have our talents. Math is not one of mine. Practice and seeing it done is my way to learn. But my mind wants to know why and I get mad at myself when I do not get something. Character flaw. One of many.
OK..yes...so using the bigger hose analogy,,,think of the resistance of the build (the completed coil or coils) and the resistance of the wire as two separate things right now...although they both play to the beat of the same drummer.
Overall, it is the resistance of the build that drives how much power can flow to your atty
But the wire is the same concept at a more basic level. A 28 Gauge wire is a thicker hose and is actually fatter than a 30 Gauge wire. This you know.
Each gauge of wire has a native resistance. The fatter the wire (bigger the hose) the less resistance it has on its own. We increase resistance on a wire by wrapping it into coils. This is why it takes more wraps on 28 gauge to get to (say) 2.0 ohms than it does on 30 gauge to get to the same 2.0 ohms. Because 30 gauge has natively more resistance being a thinner wire (smaller hose) it takes less wraps to slow it down to 2.0 because it is already slower. So to slow down the fatter hose you have to put more kinks (coils) in it...LOL
