A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
With sufficient voltage, everything is a conductor.
With insufficient voltage, everything is an insulator.
Neither may be conducive to those roles, but everything has some conductivity and some resistance (super conductors being a possible exception).
How about in vacuum? Do you get fancy arcs or glows or what?
In typical conditions, an electrical arc forms when the electric field strength exceeds the dielectric strength of the medium (like air). In a vacuum, there is no medium to ionize, which theoretically makes it difficult for an arc to form. However, electricity can still arc in a vacuum under certain conditions, such as when high voltages are involved or when the electrodes are extremely close together.
I was thinking neon lights. I mean that's basically an arc, just spread out. I think I heard that there's a glow in vacuum too, just not as nice as with neon.
Well, a quick search turned up this: Vacuum Arc
However, like the above comment, it seems to refer to freeing electrons from the conducts, so, IMHO, you no longer have a vacuum.
If you could somehow maintain a perfect vacuum; I wonder how this concept Virtual particle would come into play (or if it would at all).
Oh hey, I design those. Though I design them so that there's an incredibly low risk they do that.
Boorring, we want sparks ✨️
...and DEATH
I'll see what I can fit into my next design

Everything is a wire if the voltage is high enough.
Every machine is a smoke machine if you use it wrong enough.
I was interviewed for a position where lady handed me a pen and asked if it was a conductor.
I replied: "if the voltage is high enough, yea. She scoffed. Needless to say, I didn't get the job.
Honestly I think you gave the experienced adult answer to what was a high school or even middle school science question.
that just sounds like a weird interview.
"you're qualified for this position if, and only if, you can answer a useless question with only a rudimentary understanding of the subject and no critical thought"
if true, you dodged a bullet
High frequency! It Mega hurtz!
Low frequency! It kill a hurtz!
Ultra high frequency! It giga hurtz!
Pretty much any high voltage high frequency thing really hurtz. It'll kill you at different rates but it'll hurt the entire time.
Low voltage: "Oh no, there is a tiny spot of corrosion on the contact surface, I think I need to lie down..."
High voltage: (rips line of coke) "I'M GONNA MAKE MY OWN WIRES WITH BLACKJACK AND HOOKERS!"
This is particularly applicable around downed power cables. Do NOT approach. You don't need to touch it to become the wire.
For example: in LA right now
dO nOT toUch the DoWn wIres uuuum I have MY RIGHTS to turn myself into a gas station hotdogs thankyouverymuch
You have to keep in mind that the resistance from one foot to your other is going to be less than dry earth between your strides. This means if you are walking toward a downed power line, you may inadvertently walk within its path to its ground and the voltage could actually travel through you.
When you cast Chain Lightning at nothing.
Everything is wire if the voltage is high enough

Pshaw, even at LV, it's a lay theory that is, at best, vastly incomplete and, at worst, demonstrably false.
Electricity will flow through all paths, the most electricity will flow down the path of the least resistance.
That arc is going up because the plasma is hot and the air is turbulent.
Yeah, maybe it needs a Hedberg-ism to get it across to people.
Electricity takes the path of least resistance. It takes the other paths, but it takes the least resistance path too.
"it's current not voltage that kills you"
High voltage: "Por que no los dos?"
High voltage: “hey bestie, how would you like a ✨️new and improved ✨️ nervous system?”
I think that still is actually from this video of a switch opening. Sound on, it's real neat.
modern metal band logos are really getting out of hand smh
This is so accurate. Try reading this without knowing what it is. It's impossible

I don't know too much about HV, but I thought that even the crazy path shown in the picture was still the path of least resistance. Is that wrong?
Dielectric breakdown, literally carving its own path of least resistance through the air.
You might not like it, but this is what peak conductivity looks like
Looks like a mad scientist cackling a maniacal laugh.
From what I've seen, nothing will make a bunch of linemen hit the deck like the sound of high voltage switchgear opening when they weren't expecting it.
"NNNNYYYYYYAAAAAZZZZZZZZZZTTTTT"
Its funny because the arc looks a bit like Louise Belcher laughing maniacally
