How do electrons find the “path of least resistance”? [video]
The video is interesting, but I suspect, that the author is making some subtle errors at places. Tho I'm not 100% sure, last time I analyzed those subject was at BsC/MsC courses at my uni.<p>E.g. he says something to the tune of<p><pre><code>   electrons take a few ns. running around, and then settle down in the maze.
</code></pre>
IIRC electron flow in a medium is relatively slow, something on the order of centimeters per second. So it's not electrons which settle some potentials by moving quickly, but the electric potential finds its equilibrium. And it finds its equlibrium by electrons exchanging virtual photons (carries of electromagnetic force)?
