(don&#x27;t want to nitpick) Chromodynamic? As in QCD? We certainly are not probing anywhere near those regimes :) Also, conductivity is not the thing to think about, arcing has to do with dielectric breakdown. I guess my loosey-goosey explanation (less stuff to support current, as in less valence electrons to get stripped off to actually make a current from negative to positive plates) confused it a little.
