Electric current

    why electric current flows at speed of light when we know that current is due to the drift velocity of electron which is only few km/s(i think)?

    hi asad1111! :smile:
    no, the electric field travels (away from the electrons) at the speed of light

    the electrons themselves get left behind! :biggrin:
