Abstract
Abstract In its more modern context, the Drude–Lorentz model views a material as consisting of an array of the following: fixed positive ions and free electrons; or neutral atoms, or balanced positive and negative ions atoms (as in NaCl), with no free electrons. The first case involves a metal while the second involves an insulator. This chapter derives expressions for the following: electrical conductivity and electrical resistivity of metals at room temperature; the Hall effect; frequency-dependent conductivity; dielectric constant of a metal; dielectric constant of an insulator, a metal in a constant magnetic field and an oscillatory electric field; thermal conductivity of a metal; and thermoelectric effect. The chapter also includes some sample problems.
