I won't give money to Shill Nexus by playing their videos but I've seen the screenshots.
Current generates heat, usually not a big deal unless there's a problem with the materials used or the amount of them.
I did. I was in trades school and we made different tests on wiring and other materials to 'see' how they behave when you do different things to them.
A piece of thin wire will melt differently with AC vs DC, with AC it'll cut usually in the middle, and with DC in the end that's further away from the power supply. In theory the same would happen to the filament inside a light bulb, but it's a much slower process I didn't have the chance to witness yet. If you grab a burnt bulb that's been working with AC you'll see the filament cuts in the middle, and -in theory- if you get a burnt bulb that's been working on DC the filament will be cut at the end that's closest to the negative side. The experiment can be done with a fluorescent lamp too, under overvolting conditions only one of the ends will darken.
I've mentioned before low quality chinese space heaters are the #1 cause of house fires involving electricity where I live but the interesting thing to us is that it's not the actual heaters that cause the fire, but the wiring or the interconnection elements (in normal terms, plug and socket). If you plug in a thing that constantly draws 10-12 amps from a wall socket it won't be long until something melts or causes a spark when the wiring is poorly done.
Since there's nothing like an EICR that has to be done here, most houses the wiring is an absolute nightmare, it's either from the 50's or made out of pieces of wires of entirely different gauges put together, and nowadays different materials as well, because so called "electricians" are using aluminium or alloy wires because they're cheaper. A wire of a made out of pure copper
Oh, and since Chinese stuff comes with a Chinese plug you have to use an adapter to fit them in a socket (ideally you'd replace the plug but nobody does that), and the more things you add the more resistance they offer against current = heat = fire.
The smaller you make things the less current you can run through them. You can increase the voltage to cope with it but only up to certain point. If you fed 12V to a CPU it'd have to be physically larger to deal with that, even if it draws a fraction of the amps it would when running at 1.2V
There's a bunch of boring physics explanations for this you can read on the internet or books on electrical engineering.
