Electricity does not take the path of least resistance. It takes every path available, inversely proportional to that paths resistance.

When the voltage gets high enough, it will literally start ripping molecules apart in order to make its own path.

Also, nice meme, nerd.

[-] Dabundis@lemmy.world 111 points 11 months ago

It takes every path available, and with high enough voltage, more paths become available

[-] sukhmel@programming.dev 48 points 11 months ago

That's just a new game plus for electricity

[-] turddle@lemmy.world 8 points 11 months ago

AC + high voltage must be nightmare mode

[-] sukhmel@programming.dev 8 points 11 months ago

I'm not an electrician enough to say, but if I remember it right, AC + high voltage is what Tesla generators use to generate all that fancy air zaps. That's more high frequency than the consumer grade AC, and high frequency makes it somewhat safe for living things because electricity doesn't flow deep into the body in that case.

[-] turddle@lemmy.world 3 points 11 months ago

Yep! Once you start getting into waves & fields all bets are off. High frequency electromagnetic radiation gets more and more wild if you back it up with enough power

Could be as safe as a radio transmission or as deadly as a submarine’s sonar pulse. All depends on the frequency and the power behind it (and where you direct it)

yeah what's this about?

[-] empireOfLove2@lemmy.dbzer0.com 78 points 11 months ago

High voltage be like: "Fuck you. I'm gonna make my own wire, with blackjack and hookers (and ionization)!"

[-] RubberElectrons@lemmy.world 8 points 11 months ago

Never mind carbonizing the path it took along the PCB so future breakdown happen at much lower voltages 😑

PCBs: ✅ Fucked Your shit: ✅ Also fucked Your day: see above

😉 on purpose, in fact

[-] muzzle@lemm.ee 6 points 11 months ago

High frequency signals be like: wires? Where we are going we don't need wires!

Thank you for sharing this. I was enthralled from start to finish.

[-] A_Union_of_Kobolds@lemmy.world 33 points 11 months ago

You'll have that when your voltage overcomes the resistance of the air

[-] RubberElectrons@lemmy.world 4 points 11 months ago

Sometimes it happens even below the arc breakdown voltage via air... Air molecules are slightly less dense along the surface of a smooth flat surface due to molecular 'bounce', so electrons creep along the lower density of a surface.

Hence, creepage on a PCB.

High frequency signals be like: conductors? Where we are going we don't need conductors!

[-] frezik@midwest.social 19 points 11 months ago

What's the center of this copper wire even for, anyway? I'm going around the edges.

[-] henfredemars@infosec.pub 7 points 11 months ago* (last edited 11 months ago)

True that. I was amazed how many hundreds of amps I could dump into an aluminum foil antenna at high frequency.

Just aluminum foil around PVC is practically as good as solid aluminum pipe.

So... something weird happened with my phone, and I thought I clicked a link for electricity solving a maze and got this instead and it was... a uniquely confusing experience.

But also weirdly nostalgic for back when confusing things happened on the internet all the time so... thanks?

[-] pleb_maximus@feddit.de 5 points 11 months ago

You are welcome. We all need some more of that old internet.

[-] Zacryon@lemmy.wtf 15 points 11 months ago

Everything is a resistor. It's just a question of voltage.

[-] Silentiea@lemmy.blahaj.zone 1 points 10 months ago
[-] lud@lemm.ee 2 points 10 months ago

Super bad resistor you mean.

[-] Norgur@fedia.io 12 points 11 months ago

Why is high voltage that hard to read?

[-] Ozzy@lemmy.ml 32 points 11 months ago

zalgo used to represent the demonization of high voltage

[-] mossy_@lemmy.world 23 points 11 months ago

it's also a reference to an existing meme

[-] A_Union_of_Kobolds@lemmy.world 15 points 11 months ago

Because it follows every path at the same time

[-] Draconic_NEO@lemmy.dbzer0.com 11 points 11 months ago

Silicon isn't a conductor, it's a semiconductor. Also conductivity is dependent on temperature, hot stuff usually conducts easier, though some things conduct easier when they are colder. Even at the low voltage it's more complicated than "Conductors" and "Insulators" we learn in those ultra basic electronics guides online (or in school if you're lucky).

[-] Gladaed@feddit.de 5 points 11 months ago

Hot stuff always conducts. As in plasma.

[-] Draconic_NEO@lemmy.dbzer0.com 1 points 10 months ago

Except superconductors often conduct better when they are cold (unfortunately, would be nice if a room temperature one was found but probably isn't going to happen).

[-] LemmyKnowsBest@lemmy.world 10 points 11 months ago

Thank you for this powerful visual. I've always had trouble understanding electrical concepts, but this is beginning to open my eyes now.

[-] pico@sh.itjust.works 10 points 11 months ago

More like where is the ground

[-] purplemonkeymad@programming.dev 7 points 11 months ago

The path to neutrality by any means nessasary!

[-] Sam_Bass@lemmy.world 6 points 11 months ago

In HV anyo...thing can be a wire

[-] ramble81@lemm.ee 5 points 11 months ago

Would it look for a wire or more so “where is the fucking ground”?

[-] The_Tired_Horizon@lemmy.world 4 points 11 months ago

Can confirm. Built a mini Van de Graaff as a kid.

[-] TheObviousSolution@lemm.ee 4 points 10 months ago* (last edited 10 months ago)

If electricity is a highway, current is the number of cars at any given time, voltage is how fast they are going, and high voltage are the driving sequences from The Transporter / Fast & Furious movies.

[-] Ranger@lemmy.blahaj.zone 2 points 10 months ago

I can hear this meme.
