The
Drude model of
electrical conduction was proposed in 1900 by
Paul Drude to explain the transport properties of
electrons in materials (especially metals). The model, which is an application of
kinetic theory, assumes that the microscopic behavior of electrons in a solid may be treated classically and looks much like a
pinball machine, with a sea of constantly jittering electrons bouncing and re-bouncing off heavier, relatively immobile positive ions.
