I think the plasma in this medium should have a shockwave component. As the plasma progresses, it compresses the gas ahead. But if the gas has a polar nature, it will tend align its charges to perpendicular slightly ahead the shock wavet. Such alignment should make the gas ahead of it work a lightining rods elongating the wave front. So, the plasma would ride behind a hot wave front. The resistance should be smaller.
Here is a description of the model by Sing Lee http://www.plasmafocus.net/IPFS/modelpackage/File2Theory.pdf
It’s a bit maths heavy, but you can skip most of the equations and just read the explanatory text.
