Details about electrons moving in a wire, --interesting Youtube video Options

[Dave_Darling]

Very very tangential relevance to 914s, but if you ever wanted to know details about electrical flow in your electrical system...

This video focuses on what happens when you have one pair of wires connected to another pair in a Y configuration, but it also contains information on how electrons flow through a circuit--

It's very neat to watch the visualization of the "wave" of voltage (and similar wave of current flow) that propagates down the wire. The way he set up the measurement is very complicated, but the results are awesome.

My real job is working on computer systems, seen flaky things with signal termination and reflection for years.

Not so much on static DC voltage connections like our teeners, although the FI/ECU wiring could be affected.

The part that stood out for me in his video was the fact he shorted the end of his 'terminated' wires rather than put an actual load on it. The 9v battery has a rather small amperage capacity that it can generate so after the initial pulse, it would discharge/drain the battery down to nothing in a pretty short time.
I want to see him do this same test with a fully charged 914 battery. The initial current pulse will probably be about the same length of time, but a LOT higher as it lets all the smoke out of the wires...
Closer to reality for some of us.
