Abstract
THE electrical resistance of a metal arises from the scattering of the electron waves passing through it. The fraction of these electron waves scattered in all directions in a unit volume, which will be called the attenuation coefficient, μ, is equal to the reciprocal of the mean free path of the electrons. From this the specific resistance ρ can be calculated from the formula
