Conductivity, Electrical


(or conductivity), a physical quantity equal to the electrical conductance of a cylindrical conductor of unit length and unit cross-sectional area. The relation between conductivity σ and resistivity ρ is given by the equation σ = 1/p. Conductivity is usually measured in units of mho/m or mho/cm. The mho, also called the Siemens, is equal to the reciprocal of the ohm.

Drude model of the electrical conductivity of metals [1,2], considers that in this medium the free electrons (the electrons in conductors) undergo Brownian motion with an average characteristic time [tau] between collisions.
Therefore the analogy developed in this work between black hole physics and the electrical conductivity of metals is very encouraging.
Drude formula for the electrical conductivity of metals can be written as 2
