These examples are quite different. Experiments in one cannot be used to
make an inference in the other. One is electric flow, the other is
photons. The physics are not even close to the same. Which one do you
want to talk about?

Current flow in lumped circuits is assumed to take
place instantaneously, i.e. faster than light speed.
In a DC steady-state, there is no acceleration of
carriers and therefore, no photonic particle flow so
the above shortcut works in that case. It doesn't
work in RF distributed networks where photon generation
and absorption never ceases. One of the boundary
conditions for EM wave flow is that is can never exceed
the speed of light c(VF).
