What keep electrons move? I read somewhere that in q physics the kinetic energy of an electron mean how much the wave cloud is compressed. If the electron is part of an atom its wave is wide a smeared but if delocalized then its wave is small and its position much more exact. But the electron can move/flow in a conductor. That's different moving? It has two kind of "moving"? And this classical moving also constant, e- always move as a wave and as a particle too?
