Electrical resistivity and conductivity - Wikipedia
WebElectrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter σ ( sigma ), but κ ( kappa) (especially in electrical engineering) [citation needed] and γ ( gamma) [citation needed] are sometimes used.
6.3: Conductivity - Physics LibreTexts
WebConductivity is one of the three primary “constitutive parameters” that is commonly used to characterize the electromagnetic properties of materials (Section 2.8). The key idea is this: Conductivity is a property of materials that determines conduction current density in response to an applied electric field.
Conductivity (electrolytic) - Wikipedia
WebConductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m).

Electrical Conductivity of Metals - ThoughtCo
WebMar 2, 2020 · Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.
Thermal conductivity and resistivity - Wikipedia
WebThe thermal conductivities of common substances span at least four orders of magnitude. Gases generally have low thermal conductivity, and pure metals have high thermal conductivity. For example, under standard conditions the thermal conductivity of copper is over 10 000 times that of air.
