#snsinstitutions #snsdesignthinkers #snsdesignthinking Drude model treats conduction electrons in metals like molecules of an ideal gas.Valence electrons detach from atoms and move freely through a fixed lattice of positive ions.Thermal velocity drives random electron motion until an applied electric field causes directional drift.Collisions with the positive ion cores cause resistance and limit the final drift velocity.Limitations include failing to explain the specific heat capacity and temperature dependence of conductivity.
