In this video, I measure a wave of electricity traveling down a wire, and answer the question - how does electricity know where to go? How does "electricity" "decide" where electrons should be moving in wires, and how long does that process take? Spoiler alert - very fast!

I've been very excited about this project for a while - it was a lot of work to figure out a reliable way to make these measurements, but I've learned SO much by actually watching waves travel down wires, and I hope you do too!

There will be a Q&A about this video posted in a few weeks on the second channel, and if you head over there right now, you'll see two direct follow ups to this video with experimental details, and a section about "impedance matching" that was cut from this script.
