IEVref: 121-12-02 ID: Language: en Status: Standard Term: conductor (general sense) Synonym1: conducting medium [Preferred] Synonym2: Synonym3: Symbol: Definition: medium in which a time-varying electric field produces an electric current density the component vector of which in a given direction has a magnitude large compared with that of the component vector of the displacement current density in this direction, in a particular frequency band NOTE 1 – Under sinusoidal conditions in an isotropic medium, the medium is conductive if the following relation is satisfied: $\frac{\gamma }{{\epsilon }_{0}\omega }\gg {{\epsilon }^{\prime }}_{\text{r}}$ where γ is the conductivity, ε0 the electric constant, ω the angular frequency and ε′r the real relative permittivity. Under static conditions the medium is conducting if the conductivity is not zero. NOTE 2 – An anisotropic medium can be conducting only in certain directions. NOTE 3 – The term “conductor” also denotes any element intended to carry electric current.
