Testing How Electricity Signals Travel Through a Kilometer of Wire
AlphaPhoenix · Demo · YouTube title: I bought 1000 meters of wire to settle a physics debate
Why it's here
HN considers it the best experimental rebuttal and clarification of the Veritasium wire debate, with real measurements.
What it covers
AlphaPhoenix builds a scaled-down version of the Veritasium electricity thought experiment using about a kilometer of wire and an oscilloscope. He measures how the signal actually propagates and explains the result.
