Correct me if I'm wrong, but this sounds like the electrical version of "water hammer" in pipes. The electrons have velocity. When you suddenly change the impedance of the medium, the extra electrons already on the medium that can no longer fit into the transition will bounce back.
- fsociety 3y agoThinking of an electron as a thing that travels from the start of the circuit to the end results in a bad mental model. Think of it as a wave, and then watch this video https://youtu.be/DovunOxlY1k https://youtu.be/DovunOxlY1k. Then you will have a strong mental model.

- mikewarot 3y agoFun fact, the average speed of an electron in a circuit is typically that of a snail, unless you're really, REALLY heating up the wire.
- AdamH12113 3y agoI think a better analogy for water hammer would be inductance. Trying to suddenly open an inductive circuit (close a valve) produces a voltage spike (pressure spike).
