sähkönjohtavuutena
Sähkönjohtavuus, often referred to as electrical conductivity, is a fundamental physical property of a material that quantifies its ability to conduct electric current. It is the reciprocal of electrical resistivity. Materials with high electrical conductivity allow electric charge to flow easily through them, while materials with low conductivity impede the flow of charge.
The conductivity of a material is determined by the availability and mobility of charge carriers, which are
The SI unit for electrical conductivity is siemens per meter (S/m). A material with a conductivity of
Common examples of highly conductive materials include silver, copper, gold, and aluminum. These metals are widely
