Classical free electron theory could not explain many physical properties. This drawbacks of classical theory can be rectified using quantum theory. The failures of classical theories were removed by Sommerfield in 1928. He...

The classical free electron theory has been successfully applied to explain the various properties of metal. It is used to verify Ohm’s law It is used to derive Wiedemann-Franz law. It explains the electrical and thermal...
The electrical conductivity is defined as the rate of electric charges flows across a unit area in a unit time per in a conductor per unit potential gradient (or) electric field. It is denoted by σ. Expression for electrical...
Drude – Lorentz Theory In 1900, Drude was first to explained metallic conduction on the basis of his free electron theory. In 1909, H.A. Lorentz modified this Drude model by applying Maxwell-Boltzmann statistics on the...
