Wire Gauge and Resistance for Rebuildable Atomizers

Higher Gauge = Thinner Wire = Higher Resistance

Anyone interested in rebuildable atomizers or even rebuilding clearomizers will eventually have to make a choice on what wire to use.  Wire thickness is referred to by gauge, but there is often little information regarding what gauge to use.  A few tips should help you make the choice.

First, let’s be clear that there is no “right” choice.  Different wire thicknesses work better for different applications, but a lot is up to personal preference.  There are really only two things you need to remember:

Higher gauge wire is thinner.  

Lower gauge (thicker) wire has lower resistance.

In practice, this means that more wraps of lower gauge wire are needed to make the same resistance coil as less wraps of a higher gauge wire.  For example, 5 wraps of 32 gauge will make a coil with around 2.0 ohms of resistance, while it will take around 8 wraps to do the same thing with 28 gauge.

For standard ohm applications in the 2.0 ohm range, nearly any gauge between 28 and 34 will do the trick.  30 or 32 will make a nice warm coil that fits in an EVOD head, for instance.  Lower gauge becomes very important for those looking to build extremely low resistance or even “sub-ohm” coils.  By the way, I highly recommend getting comfortable with building standard resistance before tackling low resistance – too many bad things can happen to batteries when the resistance is too low.
