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.
For example: in LA right now

EtherWhack@lemmy.world 3 months ago
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.

Why is this not knowledge taught in school?
It is the first time i hear about it and i have never thought of it, yet it makes total sense and could make the difference between life and death in a storm damaged area.

That’s so interesting. Thanks!
Naich@lemmings.world 3 months ago
The safest way to do it is to get someone else to touch it first.
tibi@lemmy.world 3 months ago
Especially dangerous if it’s a high voltage wire. Even standing close you can become the least resistant path to earth.
Estebiu@lemmy.dbzer0.com 3 months ago
For downed, you mean just a power cable that’s down on the ground but otherwise intact, or he’s only dangerous when cut?
MataVatnik@lemmy.world 3 months ago
Any cable that’s not where it’s supposed to be, just stay the fk away 👌 Even if it isn’t visibly cut there could be a short somewhere

I was interviewed for a job where lady have 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.
KreekyBonez@lemmy.world 3 months ago
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”

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!

High voltage: “hey bestie, how would you like a new and improved nervous system?”
WolfLink@sh.itjust.works 3 months ago
I always thought that was a dumb saying because voltage is specifically what allows there to be a lethal current.
candybrie@lemmy.world 3 months ago
I think people just don’t understand ohm’s law. They seem to think voltage and current are unrelated to each other.
SaharaMaleikuhm@feddit.org 3 months ago
Hence the signs saying “DANGER HIGH VOLTAGE”
druidjaidan@lemmy.world 3 months ago
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.
booly@sh.itjust.works 3 months ago
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.
mexicancartel@lemmy.dbzer0.com 3 months ago
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)
Arrkk@lemmy.world 3 months ago
10kV static discharge and 5kA @ 1mV would like a word.
ulterno@programming.dev 3 months ago
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.
ThePyroPython@lemmy.world 3 months ago
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…

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?
MataVatnik@lemmy.world 3 months ago
Dielectric breakdown, literally carving its own path of least resistance through the air.
jjagaimo@sh.itjust.works 3 months ago
You might not like it, but this is the peak conductivity
kerrigan778@lemmy.world 3 months ago
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.
rumba@lemmy.zip 3 months ago
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.
Zink@programming.dev 3 months ago
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.
rumba@lemmy.zip 3 months ago
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 lineman hit the deck like the sound of high voltage switchgear opening when they weren’t expecting it.

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.

Trigger2_2000@sh.itjust.works 3 months ago
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).
big_fat_fluffy@leminal.space 3 months ago
How about in vacuum? Do you get fancy arcs or glows or what?
MataVatnik@lemmy.world 3 months ago
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.
