      I mean, yea. The people designing the AC to DC power supplies often don’t care what you use them for, why would they bother putting schematics for a real load on their diagram?

        It’s a basic AC rectifier, the resistor represents an arbitrary DC load. You use similar circuits all the time, though generally with additional failsafes and some mechanism of smoothing out the rectified current.

      That’s not a resistor it’s actually a BIG LOAD. The diagram would better show it as a reactive load (usually just a rectangle) since most real loads are reactive. Get it?

          And in this specific application (simple resistor as a load) you could even save all the diodes and generate even more heat in the resistor alone instead of also „heating“ the diodes. *

          This my most favorite circuit. It’s a very simple and elegant solution doing its job in silence without getting the kudos it deserves.

    Said it before and I’ll say it again: just because you understand the magic doesn’t make it any less magical. A wizard may know the ins and outs of their spells, but they’re still spells. Our entire universal is fucking magical, we just happen to have a decent understanding of why (some) of it functions the way it does. Jiggle a quark here and another may jiggle the same way somewhere in the vicinity of Betelgeuse, that’s fucking wild and magical and incredible, and just because we have some level of understanding behind the mechanics doesn’t make it not magic. It just makes it a hard magic system.
