@nasu [3] I personally disagree on the electric field in conductor interpretation, superconductor requires no field for electron to continue to circulate, voltage does not drop in a conductor, it drops a lot a resistor, yet the current flow is the same.

@nasu just to confirm: [1] free means electrons can move between nucleus (metal) or move between lattice (semi conductors) or really free (a gas of electron) [2] not due to pushing: so conduction in microscopic view, could be due the the absence of other electrons in the direction of conduction (an hole moves in a semiconductor, or this electron moves left because the electron on this electron's left have moved left already leaving a vacancy)
