Watch electricity hit a fork in the road at half a billion frames per second
AlphaPhoenix
AlphaPhoenix uses a custom high-speed measurement setup to watch voltage waves travel down wires and split at a fork. It answers how electricity knows where to go and how quickly that process happens.
Praised as the clearest visual explanation of transmission lines, impedance and signal propagation, with several commenters saying it made it all click.
