2) The number density of conduction electrons in silver is 5.86 x 1028 m-3. independent of temperature. If a cylindrical wire of length L and cross-sectional area A were made of silver its electrical resistance would be given by R= ρ L A where ρ is the resistivity of the material measured in Ω−m. The resistivity can also be shown to be related to microscopic properties of the metal such as the number density of conduction electrons, the mass and...
