In this video, I try to explain electricity Ohm's Law… using a LOT of different demonstrations and analogies. I've been working on this script for like a year and a half now - this took SO long to assemble because electricity is an absolute pain to learn and to explain. I crammed every analogy to describe electricity I could think of into this video (which is why it's... oof... 40 minutes... who's going to watch this?).

When I learn something hard, it's normally after I've seen it a few times before, so with a tough topic in this video, I'm trying to scatter-shot and hope that at least one demo clicks for everybody! If it DOESN'T click for you, let me know what's weird! There will be an FAQ about this video posted on the second channel in a few weeks. If you want to ask a question, drop it in the comments here, or if you want to make sure I see it, leave a note on the new Patreon Discord server!

The biggest intentional omission in this video is not addressing radial charge distribution in a wire, and I know that's going to annoy some of the commenters here. I only talk about 1D wires so I don't have to confuse people by making them imagine different families of electrons at different parts of the wire when at the end of the day they can all get squished and move the same way - so please consider all of my diagrams with electrons getting "more concentrated" to be looking all the way through a wire, including the surfaces :)
