RF elecronics @discuss.tchncs.de nothacking @discuss.tchncs.de A simulation of a very long circuit.
A simulation based on maxwell’s equations and ohms law of a very long circuit, demonstrating how current can seem to travel faster then light.
This is actually the exact same effect as the characteristic impedance of a transmission line, while pulse is traveling down it, the transmission line will appere to have a particular impedance, regardless of what is on the other end.

Not exactly useful as the simulation is 2d, but cool.
