Summary:
Written by Derek Muller and Petr Lebedev.
The misconception is that electrons carry potential energy around a complete conducting loop, transferring their energy to the load.

Special thanks to Dr Geraint Lewis for bringing up this question in the first place and discussing it with us. Check out his and Dr Chris Ferrie’s new book here: https://ve42.co/Universe2021 Special thanks to Dr Robert Olsen for his expertise. He quite literally wrote the book on transmission lines, which you can find here: https://ve42.co/Olsen2018 Special thanks to Dr Richard Abbott for running a real-life experiment to test the model. Huge thanks to all of the experts we talked to for this video — Dr Karl Berggren, Dr Bruce Hunt, Dr Paul Stanley, Dr Joe Steinmeyer, Ian Sefton, and Dr David G Vallancourt.
