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.
  
  Arc flash hazard training messed me up. They showed a video where a guy is working on some switchgear when suddenly the frame is all white and then the guy is just GONE, but the floor and everything around where he was is a different, very red, color. That "if" regarding survival is doing some heavy lifting.
  
  Thanks, I hate it
  
  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
- I'll make my own path! With blackjack!
- Exactly what happened here! In the video the arch starts in a much more straight line, and rises as you describe as the air heats up.

Meanwhile in semiconductors: 5V is high voltage

this and potatoes are nightmare fuel in their own unique ways
- Excuse me, what
  
  HAVE YOU SEEN THE HORRIFIC SHIT POTATOES DO WHEN THEY LOOK FOR NUTRIENTS
  
  Also, a prolonged sun exposure makes them poisonous with arsenic-like chemicals unless you hide them indoors or cook them. You can tell by seeing them turning green, like poisonous potatoes in Minecraft. It's not THAT lethal, but can teach a human or an animal a lesson that even if you see a potato on the surface, don't feel lucky about it, don't dig, it'd fuck you up.

High frequency signal: where we are going we don't need wires!
- HF signal when piece of paper or thin drywall: I don’t feel so good boss

anyone else kinda see a wolf sorta screaming at the sky with the right hand held up with a fist
- Now I do, but why does it have so much hair?

Anything's a wire if you piss off the pixies badly enough.

::stares at image for five minutes just to make sure I'm not missing a metal-band logo reference in there somewhere::

Well, there's no "insulator". There are only semiconductors.

Shocking
- I think the arc looks a little bit like two people.

I refuse to believe this isn't an AT-ST.
