Watch electricity hit a fork in the road at half a billion frames per second
A 26-minute video by AlphaPhoenix about electrical signals and circuits, on the Physics shelf. It came up in 5 Reddit threads, in r/Physics, r/explainlikeimfive, r/AskPhysics and r/codyslab. It is pitched at introductory level.

Measures electrical wave propagation through a branching circuit to explain how signals respond to available paths.
Study notes
Introductory, Experiment. Step 2 of 6 in The physics under electronics
Helpful first
- Basic circuits
- Voltage and current
What it builds
- Measure electrical waves travelling down wires.
- Understand line impedance through experiment.
- Observe current splitting and reflecting at a branch.
Useful moments
Check yourself: Why can the initial response of a long wire differ from its steady-state behaviour?
