Kind of like how a piston in an engine also kinda just “shakes about” (because of explosions or steam or whatever) and yet delivers a lot of power.
Elections merely facilitate the transfer the power, like (the non-leading edges of?) a drive shaft or cogs.
Even with DC you need a loop (well, a difference).
Carbon fuel one-use mentality where you burn your supply (chemically stored energy) doesn’t apply, tho non-rechargeable batteries make it seem so.
It’s even crazier than that. It’s not even the electrons at the “leading edge” it’s the EM field they create even separate the of the wires that actually contain the electrons.
And the follow-up with a physical experiment after the first video started a huge drama.
No, the leading edge of the mechanical transfer of power - I was trying to make a faux comparison that electrons would be the inside of the shaft/cog & the fields the leading edges (that transfer the power & are moving more).
I mangled the comparison, should have given up on it. Vibes are hard to compare with anything non-vibes.
Great youtubing in the links, that’s how you get them views (benefit several creators and spread science)!
(*I just skimmed them for the general vibe, I’m not voicing support in case they are weird ppl, I don’t know them.)Edit: while speeding through I noticed a very cool simulation (software), yt/mcez0ri9yPY, these are very neat visuals.
God I hate that video, he explains everything so badly to the point of completely misinforming viewers. He’s talking about a special situation of AC current, but uses DC in the thought experiment. He makes it seem as if the field travels to the load in a direct path and the wires don’t matter. No, the EM field is completely based on the wire.
non-rechargeable batteries
Yeah, why are they still a thing? Recharchables have all the advantages but more.
Low self discharge. Good for ultra low power devices like remote controls or lights only used on occasion where a rechargeable battery would self discharge faster than the rate of actual use.
Ah right, i forgot about that.
Let’s hope those paper batteries by Flint (shown at CES) aren’t bs marketing (that they truly aren’t harmful as waste & are comparable to normal batteries).
Yep, exactly why it works so much better over distance than DC.
That’s not correct. What you need for long distance is high voltage, and it’s easier/cheaper to step up/down AC voltage than DC. If conversion costs were eliminated, DC is actually more efficient.
If you get to even longer distances of over 300+ miles, DC’s efficiency becomes worth the additional cost of conversion. There are many HVDC interregional connections.
At distances closer to a quarter wavelength you can also have some pretty gnarly reactions if a line goes down. That’s why stuff like the Kahora Bassa power plant uses HVDC for transmission.
In an AC system, the pedastal fan in your bedroom is electromagnetically coupled to the turbine at the coal/gas/hydro/nuc power station. They instantly and directly influence each other, and they both are spinning in tandem like two wheels on a car connected by an axel. Slowing the rotation of the fan with your hand technically increases the torque of the turbine, if only by an immeasurably small amount.
AC motors are more powerful but also more noisy. You need that power in your kitchen mixer but you need quiet in a fan. Modern WC rooms now have a DC fan, old ones have the loud one.
Fun Fact: An improperly shielded (or old and deteriorating) fan can be influenced by stray electromagnetic radiation. They’ll pick up AM radio signals occasionally, creating an off tone in the fan noise that sounds like a person talking faintly on the other side of the fan.
So you’re admitting that AI data centers vibe pretty hard? Your words!
Technically, computers are running on DC. The PSU is fed by AC but its sole purpose is to convert all the power the computer needs to DC. It’s possible to only use DC to power computers and it’s probably/apparently more efficient.
It’s just the one electron… Allegedly
Can you imagine being the guy who just, like, claps his hands together and kills the electron, snuffing out all existence
Mum says it’s my turn to use the electron!
My power company is charging me that much for nothing but vibes?!
They’re giving you excitations
Ooh, exciting!
Fyi, it isnt fully correct and a lot of electricity related channels were a bit annoyed by it. But overal its a good video hehe
Do you happen to know a good video about the issues?
AlphaPheonix has a few amazing electricity videos including this one where he actually does the experiment.
Veritasium’s video was so bad, like 15 channels made response videos within a week. Just search for, “is veritasium wrong about electricity”. It’s not that he was completely wrong, he was just doing lots of hand waving and making electricity sound like voodoo.
Thanks, this was a good watch!
Watch mehdi electoeboom and Steve mould’s follow up argument about who is right.
Thanks! I couldn’t find anything with Steve Mould but I watched ElectroBoom’s conversation with Derek and it was very interesting.
Veritasium also made a follow-up video addressing their arguments. After that, they kind of went silent and seemingly sided with Veritasium
He really showed only induction in that video, that everyone knew about. And a very small current only goes in the first pulse. Rest of the current flows as you would normally expect. Electroboom explained it pretty well and this video didn’t really disprove or argue against that at all
My main concern with his video was a lack of a real explanation. He never once used the word induction, for instance.
The AlphaPhoenix video I linked proves Veritasium “true”. It wasn’t even a rebuttal, really. It’s just that he had a problem with what Veritasium was saying about current and what it means to light up a light bulb.
Just because no one made another video after Veritasium made a follow-up one, just means everyone was tired of the subject. I have not watched Veritasium’s follow-up video because his first one offended me so much I blocked his channel. It’s not the content that was wrong, necessarily, it was the way he presented it. It was all hand waving without trying to get people to truly understand the thought experiment. It pissed me off.
(I just edited my original comment to change rebuttal to response. Also, I removed all the other links because I haven’t watched them yet, so I can’t say anything about them.)
Whats crazier is that in direct current individual electrons don’t travel at the speed of light through the conductor, but only at roughly 1cm/s.
Or, that thanks to the “skin effect” the current actualy travels in a very thin layer below the outside surface of cconductor. Most of the conductor doesn’t transfer power but only maintains the magnetic field to keep the current flowing.
No, skin effect only occurs on higher frequencies. That is why coaxial cabel is invented. But then they realized the energy in coax transfers in a completely different way.
That’s why you don’t have one thick copper cable but multiple thin ones.
I’m far from an expert, but that’s usually just for flexibility of the cable as far as I understand. Power wires inside the walls are one thick copper wire (or rather three for live, neutral and ground)
Correct, solid copper bus bars are also common in certain applications.
The voltage(electrical equivalent of force) is what travels.
It’s analagous to pushing something away from you with a really really really long stick, then pulling it back again. The stick didn’t move much but you still affected something far away.
The microwave doesn’t heat your food, it just vibrates the water.
Heat is kinetic energy and the water is part of your food, so the microwave does heat your food.
Thank you for explaining the joke
What joke?
why is everyone in this thread telling me to imagine something
Because imagination is everything- probably Einstein
Imagine an old-timey saw with a lumberjack on each side, pulling it back and forth across the tree. The saw just goes back and forth, but effective work gets done.
imagine a bicycle chain between two sprockets, if you crank it foward and back like 1 inch, over and over again, you can clearly transmit power without the chain links going much of anywhere
Theres a gnarly your mom joke in here somewhere
