15 min The Biggest Misconception About ElectricityVeritasium

This is an interesting video for those who haven't seen it Would also love to hear people who are more knowledgeable here give their opinion on this.

17 min What does "impedance matching" actually look like? (electricity waves)BetaPhoenix

You're talking about impedance matching, he did a video on his second channel about that.

Yeah, his setup is rather.... suspicious compared to the one AlphaPhoenix did, for example. There was no need for his contraption to demonstrate the effect, but he clearly wanted the largest possible initial spike for his demonstration.

Mentioned in r/AskPhysics: how do electricity actually find the shortest path?

19 min How Wrong Is VERITASIUM? A Lamp and Power Line StoryElectroBOOM

I say this with great confidence because Derek has left a comment on Electroboom's video saying as much. Hell, its the reason that Derek's current video exists.

25 min How Electricity Actually WorksVeritasium

In april 2022, Veritasium made a follow-up video (link), where he revisited the same subject, clarified some of the assumptions involved, and performed another (scaled down) real-world experiment of the original thought experiment, also showing the results of electromagnetic (EM) simulations in Ansys HFSS.

15 min What Are Electrons REALLY Doing In A Wire? Quantum Physics and High School MythsAtoms and Sporks

Using the Drude Model as an explanation for what electrons do in wires: In the Drude model, electrons are microscopic ping-pong balls and atomic nuclei are bumpers (just like a pinball machine). A video talking in simple terms about this model is here.
