1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Electrical conductivity is the inversion of resistivity, and is a measure of how well a material conducts electric current: in which Ï is the conductivity of the material expressed in Siemens per meter (S/m). In electrical engineering often Îº (kappa) is used instead of Ï.
