Watch electricity hit a fork in the road at half a billion frames per second (www.youtube.com)

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!

Let alone the waves made, this shows the falling potential through a wire which has been earthed. Great use for my high school physics class when we study this.
