| Thanks, quite the useful simulator; I hadn't found that page yet. Additional considerations for
circuit simulators: What does the simulator say about signal delay and/or propagation in
electronic circuits and their fields? How long does it take for a
lightbulb to turn on after a switch is thrown, given the length of the
circuit and the real distance between points in it? (I learned this gap in our understanding of electron behavior from
this experiment, which had never been done FWIU: "How Electricity
Actually Works" (2022) https://www.youtube.com/watch?v=oI_X2cMHNe0 ) FWIW, additionally: Hall Effect and Quantum Anomalous Hall Effect; "Tunable superconductivity and Hall effect in a transition metal

more complex than that though. |
The gap between the wires is about 1 micrometer, so light should take about 3 fs to propagate through. The simulation output approximately matches this prediction, and over the first few tens of femtoseconds the current increases, with a jump at around 70 fs due to the reflected wave. All of this is pretty much in line with the results of Veritasium's experiment.
Thanks for bringing it up. I might include this as another example in my sim.
