a lot of my ugly secrets about myself aren’t actually about me so much as areas i was underserved as a kid that i try to hide;science education and science pedagogy (teaching and the art of) just were nonexistent even in the “advanced” programs i got into. i dont remember much that doesn’t neatly fill out a scantroni need help, actually! i feel so overwhelmed by my ignorance i want to scream and wikipedia always feels so intensely judgmental, with its ivory tower aesthetic

today though i want to start small. real small.i work with and have taught people how to work with basic electronics, wiring, etc. but for the life of me ive never once heard an explanation for basic electrodynamics that didn’t leave me feeling like my mind was on fire and i needed to eject. no idea why.can someone gently walk me through (not wiki or google) how to understand voltage, amperage, and resistance? i can read formulae no prob but like. what is actually happening

more specifically, i think my problem is this: i think almost solely in analogy.which makes me good at certain things (back when, analogies as in the a:b::c:d format were on standardized tests, and i was number one top dogg on that lol) but i am really bad at one thing in particular: abstract concepts that i cant anchor to a referent pointso voltage is like pressure but not really? how does that even work? i cant think of it like hydraulics or pneumatics? i need help!

@sagebrushI think of it as an old-timey water-wheel setup. Wires are channels the water can flow through.Voltage is altitude: water starts high and flows downhill. If you're lucky you can get it to turn a wheel on the way down.Current is the amount of water that's passing. High current, more liters per second.Resistance is, well, resistance: how narrow and turbulent is the channel?
