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.
Any cable that's not where it's supposed to be, just stay away 👌 Even if it isn't visibly cut there could be a short somewhere
Everything is wire if the voltage is high enough

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.
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
Assuming that you can draw a triangle from any 3 lines, draw a triangle from lines of length 1, 2 and 3
Isn't that impossible, because let's say you use 3 as the base, the only way 1 and 2 could connect is if they were at 0 angle.

I went to a zoo the other day. Only had one animal, which was a dog. It was a shit zoo.
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!
“Danger! Danger! High voltage.

Dammit! I just got this song outta my head
High voltage: “hey bestie, how would you like a ✨️new and improved ✨️ nervous system?”
I suppose it's half right. Obviously OHMs law is the triangle.
So you get a high voltage, running through a high resistance, it won't kill you. The problem is people interpret it in a way that seems to think raising the voltage without raising the resistance is just fine.
It's kinda hard to raise your body's resistance a ton outside of not making good contact (e.g. wearing rubber boots/gloves). Things like your skin being moist lower resistance, but I'm not sure it's really that much of a safety factor when dealing with high voltage.
Voltage and current are related, of course, but Ohm's law is just a simplification of circuit theory for static circuits, and the version most are taught early on assume zero inductance and zero capacitance in the circuit. Drop in an alternating current, some capacitors and inductors, and you've got yourself a more complex situation, literally, with the scalar real number representing resistance replaced with the complex number representing impedance.
And when you have time variance that isn't a simple sinusoidal wave of electric potential coming from a source, even the definition of the word "voltage" starts requiring vector calculus to even be a coherent definition.
So when I take a simple battery of DC cells to create a low voltage power source, I can still induce current using some transformers and inductors (which store energy in magnetic field) and abruptly breaking open the circuit so that the current still arcs across high resistance air. That's the basic principle of how a spark plug works. In those cases, you're creating immense voltages for a tiny amount of time, but there's never any real risk of significant current being pushed through any part of a person's body. And as soon as you draw off some of the current, the voltage immediately drops as you deplete the stored energy wherever it is in the system.
And anything designed to deliver an electric shock to a person (or animal) tends to be high voltage, low current. Tasers, electric fences, etc.
So it's current that matters for safety. A high voltage doesn't always induce a high current. And current can cause problems even at relatively low voltages.
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.
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)
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.
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…
Wow, what's that from? It's a great speech.

What about this one?
LITERALLY NOBODY KNOWS 😭😭
First one isn't even metal. But yes. Not doing that is why anyone even remembers Party Cannon.

Ah rayatu sannon.
There's a Youtuber who has a series of videos trying to decypher metal band names.
It's quite fun
Dielectric breakdown, literally carving its own path of least resistance through the air.
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.
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.
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.
Agreed, and I think there are tons of hazards out there that would be mitigated if more people cared to learn how the world works.
But when it comes to energy in general and electricity in particular, 10x it. Typically energy is more useful when it’s more concentrated, and any potent energy source that can do a useful type of work can also do a thousand destructive types of “work.”
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
That’s fascinating!
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.
Some clever person should figure out how to do this on purpose. Badass sky displays.
Always fun stuff to work with, DI water or oil are great insulators, though one sucks to clean up if you spill it 😓
Just lather yourself up with that oil bb don't let it go to waste
Diala works great for... Cooking... Steaks. I don't know where to go with that because of how nope it is.
I WILL LITERALLY SPLIT THE AIR ITSELF
YOUR PUNY AIR CANNOT CONTAIN ME MORTALS, YOU MUST CONSTRUCT ME GREAT PILONS IN VAST SWITCH YARDS TO APPEASE ME!
(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)
👏👏👏
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).
“Gee, this squishy skin-sack full of water sure has a lot of tasty electrolytes. Might as well use this as a conductor!”
