sähkönjohtavuusmittarit
Sähkönjohtavuus, often referred to as electrical conductivity, is a measure of a material's ability to conduct electric current. It quantifies how easily electric charge carriers, such as electrons or ions, can move through a substance when an electric field is applied. High electrical conductivity indicates that the material readily allows electric current to flow, while low conductivity suggests it acts as an insulator.
The inverse of electrical conductivity is electrical resistivity, which measures a material's opposition to the flow
Metals, such as copper and silver, are excellent conductors due to their free electrons that can easily
