I have a question about this small diameter(many wraps) coil vs. fewer wraps(larger diameter coil). I believe the resistance (ohms) is determined by the length of the wire and gauge of the wire. For the sake of argument lets take the gauge factor out and consider using the same gauge for all examples.
IF you have one inch of wire its going to have a certain resistance. Lets say its 1 ohm. if you wrap that 8 times around a small wick its one ohm. If you wrap it 3 times around a fat wick its still 1 ohm. THe amount of surface contact between the wick and the coil is one inch for both coil setups. You really are not gaining any surface contact area that I can see and the ohms remain the same. In fact the larger wick maybe more efficient in wicking than the thinner coiil. My conclusion would be that using the same qauge wire the only difference would be with the wicking as the ohms and the surface contact between wick and wire would be the same.
Now this is where I really get confused. Does using a thicker wire with more wraps give a better vape than a thinner one with less wraps? THe thicker wire gives less resistance (less ohms) than the thinner wire. For arguement sake lets say the thinner wire has twice the resistance of the thicker wire. One inch of the thinner wire gives the same ohms as two inches of the thicker wire. The thicker wire therefore has double the contact with the wick than the thinner wire has with the wick. Is this the reason that many believe its a better vape? I'm thinking that perhaps with the longer wire producing the same amount of heat over its length, therefore dispersing the heat more, that it all evens out. I am not sure of this though.
My brain is twisted up now.
LT, electronically speaking, you are probably correct in regards to ohms and resistance factor between the two. I, being relatively virginal to the whole vaping game and RBA's don't know enough to know what I don't know yet! But I have began to love to experiment with this stuff, so I am driven by curiosity, guided with common sense (and street smarts) and blessed with you good folks knowledge.
What prompted me to try this coil was surface area from a hydrology standpoint.
Kinda picture a wet pipe - what happens to the water if held so it is longways horizontal? It runs down to the bottom and the top gets dry quick.
That in mind, I thought of the small coil / wick and theorize that the juice would quickly settle to the bottom in a thicker wick scenario resulting in less moist wick in contact with the entire surface area of the hot coil resulting in less vapor production? Splitting hairs? Probably.
Additionally, I understand that too much liquid cools the coil (take the top off RBA and observe how the coil doesn't get red when you hit it when the wick is wet) so I also theorize that if too much liquid is present (thinking thick wick) vape production may not be optimum? Splitting hairs? Probably.
Bottom line is I really have no clue about any if this stuff from a numbers standpoint, but I love to screw around with everything in life ( including people's minds!!!) so that has led me to ask the questions, extrapolate the knowledge, apply common sense and a whole lot of guesswork. This forum just gives me a place to share all of the hair splitting my insane in the membrane mind conjures up. I'm already trying to figure out what more i can do to tweak the coil and rolled cotton wick!
All this coming from a guy who couldn't find the rolled cotton in the box - I thought it was the wrapper. No joke. Ask Hildicat.
Thanks for your feedback LT! Rock on!
