WebOther articles where metallic conduction is discussed: band theory: In metals, forbidden bands do not occur in the energy range of the most energetic (outermost) electrons. Accordingly, metals are good electrical conductors. Insulators have wide forbidden energy gaps that can be crossed only by an electron having an energy of several electron volts. Web13 okt. 2024 · Electrical conductivity is a physical quantity that describes the ability of substances to conduct an electrical current. In electrical engineering, electrical conductivity is represented by the Greek symbol sigma. The derived SI unit for electrical conductivity is represented in Siemens per meter (S / m).

"WebFor conductivity the MegaSiemens per meter MS/m (millions of Siemens per meter) is the unit of choice. The conductivity unit %IACS is also often used. The main advantage of %IACS over MS/m is that %IACS implies measurements at 20°C (293K or 68°F) while MS/m does not specify temperature. This makes %IACS especially useful for material comparison.
