An intuitive approach for understanding electricity
Why Hacker News recommends it
HN commenters recommend it as an intuition-building explanation of electricity, especially for software people and as a counterpoint to criticism of the hydraulic analogy.

What it is
AlphaPhoenix spends about 40 minutes explaining electricity and Ohm's Law through many demonstrations and analogies, including electron concentration, pressure and flow. He deliberately scatters different explanations so at least one clicks, and he simplifies by treating wires as one-dimensional.

This spurred on some other videos from another youtuber that goes by AlphaPhoenix, he went way into all the details on it including measuring the complete flow of the wave of the electrical power and how it all works. [this video] [LINK] [LINK] (on his second channel, has a lot of "behind the scenes" of how it was done) It goes into a lot of depth of how the wave propagates, including measuring it at effectively "a billion fps" (he goes over how he does this) along the wire and how impedance matching works, etc. It's about 2.5 hours of video IIRC but it's probably the most detailed and easy to understand demonstration and explanation of all of it that I've ever seen.

Counterpoint: Youtuber AlphaPhoenix does a very good job explaining electricity using the hydraulic analogy [this video]

PEFI/PE4I as a technical reference when you need details about a specific topic, SLOC as an overall introduction to give a good intuition, and M:E for more practical project tutorials, if that’s what we (hobbyists without any formal training) end up with that would be awesome :) AlphaPhoenix YouTube channel is also a great source of information to clarify theoretical topics. I find it very helpful to just see how he think about electricity in his various projects: [this video] . And his enthusiasm is contagious! One personal note: as someone coming from software I find learning electronics pretty hard as it requires a completely different mental model and way to approach systems. Took me years of
