the path of least resistance in this case is where the air ionized, when current starts flowing it gets hot, expands and raises, making an arc. So we could blame the weird shape to thermodynamic properties over electrical ones

And that arc flash’s temperature is several times hotter than the surface of the sun. It’s hot enough to instantly vaporize any surrounding metal, meaning that if you manage to survive being near an arc flash, there’s a chance that you’ll end up with tiny metal shards in your lungs, when they cool down after you breathe them in. Arc flashes are scary stuff.

Holy crap that was a fascinating rabbit hole, thanks folks!

So as the electric field intensifies the ions do their apartheid thing and become more conductive, ultimately leading to the arc?

This will help my nightmares, I'm sure https://electricityforum.com/iep/arc-flash/arc-flash-temperature

do their apartheid thing . . .

Yeah, this should be in the Gen Chem 101 teaching manual. Lmao.
