Watch a Fascinating Demo of Collisions Inside a Conductor

AI Thread Summary
The discussion revolves around a demo illustrating collisions inside a conductor using marbles and nails to represent atomic positions in a lattice. Participants recall the setup where marbles slide down a board, consistently colliding with nails, which maintains their velocity. A request for a video link of this demonstration is made, with a suggestion to search for "marble electric circuit model.mpg." The conversation highlights the educational value of visualizing electron behavior in conductors. Such demonstrations effectively convey principles of conductivity and atomic interactions.

I remember seeing a demo of collisions inside a conductor. It was a long board with nails representing the atom positions (a square lattice arrangement) and you would put a hand full of marbles at the top. The marbles will slide down but since they keep hitting the nails the velocity will be constant.
Does anyone have a link to a video showing this demo?
Thanks!

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
