Definition

proportionality factor between electric current density $J$ (electric current density) and electric field strength $E$ (electric field strength)

J = σ E

facteur de proportionnalité entre la densité de courant électrique $J$ (electric current density) et le champ électrique $E$ (electric field strength)

J = σ E

Notes

Conductivity $σ$ is a property of a medium. For an inhomogeneous medium, conductivity $σ$ depends on position. For an isotropic medium, $σ$ is a scalar quantity; for an anisotropic medium, $σ$ is a second-order tensor.

The symbol $κ$ is used in electrochemistry (see ISO 80000-9: Physical chemistry and molecular physics).

See IEC 60050-121,locality:item="121-12-03".
