I bought 1000 meters of wire to settle a physics debate

I constructed the Veritasium electricity thought experiment in real life to test the result. If you were watching my community posts a month ago, the day that Derek over on Veritasium posted his video about electricity misconceptions, you saw me obsess over that problem a bit too much and immediately use it as the excuse I’ve been looking for for years to own my own oscilloscope. Instead of two light-seconds of wire, I used about 3 light-microseconds of wire, but it was PLENTY to resolve exactly what is happening in this circuit. I hope you enjoy the analysis! Thanks to Derek at Veritasium for his blessing to make a real-world version of his gedanken experiment. If you haven’t seen his video yet, you might want to go watch that for context, and I also highly recommend ElectroBOOM’s video on the topic and EEVBlog’s video on the topic. Electroboom’s video has some simulated scope traces extremely close to what I saw IRL, and a REALLY fantastic animation (8:27) of him waving an electron around in his hand, she
