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.
The safest way to do it is to get someone else to touch it first.
Especially dangerous if it's a high voltage wire. Even standing close you can become the least resistant path to earth.
Everything is wire if the voltage is high enough
iS iT Up tO cOde??? <--- stupidass city council 🙄
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
Oi! As an engineer I worked damn hard to trap that magic smoke in the machine only for you to let it out and try perfectly good components. Treat your machines with respect, they're getting smarter by the day and they're forgetting less and less!
Every problem is a nail if you hammer it hard enough.
"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 always thought that was a dumb saying because voltage is specifically what allows there to be a lethal current.
I think people just don't understand ohm's law. They seem to think voltage and current are unrelated to each other.
Hence the signs saying "DANGER HIGH VOLTAGE"
It's a very dumb saying. If you don't have the volts you won't get the amps to kill you that's ohms law.
However, there are plenty of harmless high voltage scenarios as well. Situations with high voltage, but no power.
So really you need both.
In static electric fields, sure. But the real world has rapidly changing electric fields, and mapping concepts like voltage or resistance to a time dimension starts to require imaginary numbers (and the complex analogue to resistance goes by a different name of impedance). And once you're modeling electricity through those concepts, you can have high current in a particular moment in time where the voltage might not be high. Or where the implied voltage is very high but was actually more of an effect than a cause.
In other words, if you're simply talking about "resistance," you're already in the wrong domain to be analyzing electrical safety properly.
Its the "power" that kills you. Power depends on you as well as voltage.(Your resistance determine the current and time period of current flow also matters)
10kV static discharge and 5kA @ 1mV would like a word.
To be precise, it's the high amount of heat, electrolysis and other chemical reactions that kill you.
If you were a prefect conductor, you wouldn't have a problem.
From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine. Your kind cling to your flesh, as though it will not decay and fail you. One day the crude biomass you call a temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal…
sadly, I never was good in music class and my sense of rhythm is bad

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
It is still the path of least resistance but it created it itself. It ionizes the air creating a channel for it and then makes the leap, creating a conductive conduit of plasma/ions, as air currents move that around the path of least resistance can get progressively more nuts because there's still a path through the ionized air.
It's a big example of a Jacob's Ladder (the climbing arc of electricity seen in science labs in movies).
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.
The problem I have with it is that it gives a false sense of security and how the world works. Most people think lightning rods attract the lightning and direct it into the ground because of this. 1/3 of the world has 220v and 110v connected directly into their showerhead without any idea why they don't die from it.
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"
I think that still is actually from this video of a switch opening. Sound on, it's real neat.
🥴 I like the way this tickles my brain
I love how the 60Hz AC coursing through the plasma (?) can be heard at a safe distance. It really conveys just how much energy is in that arc.
That’s fascinating!
Does anybody else see the beastman with safety googles and clasped hands screaming into the sky?
Some clever person should figure out how to do this on purpose. Badass sky displays.
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 WILL LITERALLY SPLIT THE AIR ITSELF

(Angle grinder sounds)
Wait... Is that a copper bus bar and a pipe? PATHETIC! NO BUS BAR IN A PIPE CAN MATCH MY ELECTRIC FIELD STRENGTH, I WILL FLASHOVER THE MOMENT YOU ENERGISE -
(Hissing sound of a gas filling a pressure vessel)
What are you doing? WAIT, IS THAT SF6?! NOOOOOOO YOU CAN'T JUST SMOOTHER ME IN AN INERT GAS WITH A HIGHER DIELECTRIC STRENGTH, I HAVE RIGHTS! NOOOOOOoooooo
(Muffled screams)
Also High Voltage. This human body will do just fine.
slaps head of a man This bad boy can fit so many volts!
“Gee, this squishy skin-sack full of water sure has a lot of tasty electrolytes. Might as well use this as a conductor!”
Noted, high voltage is potato energy.

Its funny because the arc looks a bit like Louise Belcher laughing maniacally
I thought the thumbnail was an AT-ST...
Ah shit.ya beat me to it. Dasus@lemmy.world
Oh. Well guess now you have to take me to a gay bar?
looks like lisa simpson
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.
AC current: "I choose my own path"
Danger Noodle -Me
Looks like a mad scientist cackling a maniacal laugh.
Still the path of least resistance
Or is it the path of most convenience? 🤷♀️
Sounds the same to me
We have Wireless electricity at home
Nature's free laser hair removal treatment 🧖♀️💅🏻
Is that how I can do it?! I've been looking for something for my nostril hairs lately...
Dang, this meme sparked quite some discussions.
👉😎👉
It's like one of those lichtenburg patterns, except in air.
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!"
In fact, forget the blackjack!
