Did you invent this? It's fantastic. Lots of people misunderstand electricity as just "tiny little balls colliding with other balls", or think that the electrons themselves must be zooming around the circuit, rather than the wave they participate in.
"Electron gas" sounds right to my ears for these simple analogies. Just like sound oscillates, but still moves from speaker to ear, so too does AC current oscillate, but the energy has a single direction.
- wyager 4y agoDefinitely not my invention. See also "fermi gas" which is a generalization.
- MoreSEMI 4y agoThe nearly free electron gas model is the standard introduction to explaining conduction in solids. In other words, no he didn’t invent it. Interestingly enough, the first model for explaining conduction was naively assumed to be a simple gas model. After quantum mechanics was introduced into the modeling, it was discovered that while not quite correct, it was not very far off either.
