www.phys.utk.eduthe Drude theory of conductors. This is a simple classical model, and many of its concepts extend to the quantum case. A more careful account of the Drude model can be found in the first chapter of “Solid State Physics” by Ashcroft and Mermin. The Drude model envisions a conductor as a gas of free current-carrying charges.

knzhou.github.ioThe Drude theory of metals, introduced in 1900, models a metal as a classical gas of electrons, assumed to be the valence electrons of the atoms used to form the metal. • We assume the electrons don’t interact with each other at all, the ‘independent electron ap-proximation’. However, we will allow collisions with the lattice ions.
