Hi, this is my first post here. I've been lurking around the forums for a while but never actually posted anything, which is why this post is in the new members section.
I've been thinking about why low-ohm coils typically perform better than higher ohm coils. Theoretically, with a VV device, they should be producing the same amount of watts if the voltage is bumped up accordingly.
From my understanding, oxidizing a SS mesh makes it less conductive, but it still allows some current to pass through it because it doesn't have very high ohms. How many ohms typically? I'm not sure as I've never measured my wicks.
The coils that we make though have a lower resistance than the oxidized wicks, which allows more current to pass through them as compared to the wicks.
However, as the coil resistance increases, it gets closer to the resistance of the oxidized wick. For example, lets assume the wick is 10 ohms. With a 1 ohm coil, 90% of the current goes through the coil itself, and only 10% through the wick. If we use a 2 ohm coil instead, 20% of the current is now "wasted" through the wick. If the wick resistance is even lower (5 ohms), with a 2 ohm coil, 40% of our current now goes to the wick. This is all based on Kirchoff's current law. As the resistance of the coil increases, the closer it gets to the resistance of the wick, and the greater the tendency of the wick to act as a heatsink.
Would this explain why low-ohm coils perform better? If the wick was somehow oxidized to the point where it becomes an electrical insulator, then there wouldn't be a discernible difference between a low-ohm coil and high-ohm coil. Is my assumption valid?
Thanks, and...yay, first post!
