Drude theory assumptions
Web1) What are the assumptions of classical free electron theory? Classical free electron theory of metals (Drude – Lorentz theory of metals): Drude and Lorentz proposed this theory in 1900. According to this theory, the metals containing the free electrons obey the laws of classical mechanics.

A basic assumption of the free electron theory is that the valence electrons of a metal atom become conduction electrons when there is a potential difference between the ends of a metal wire. Hence, n, the number of conduction electrons per cm 3 = Z v × 6.022 × 10 23 × ρ/W A, where Z v is the …
