    Whats crazier is that in direct current individual electrons don’t travel at the speed of light through the conductor, but only at roughly 1cm/s.

    Or, that thanks to the “skin effect” the current actualy travels in a very thin layer below the outside surface of cconductor. Most of the conductor doesn’t transfer power but only maintains the magnetic field to keep the current flowing.
