That diagram is just heat with extra steps.
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?
That's what someone who doesn't understand magic would say.
Follow the spell incorrectly and that is indeed all you would get.
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?
That's what I was thinking. Depending on the supply that'll start a fire.
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.
