sähkönjohtavuudesta
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 subjected to an electric field. Materials with high electrical conductivity allow charge to flow readily, while materials with low conductivity, known as electrical insulators, resist the flow of charge.
The inverse of electrical conductivity is electrical resistivity, which measures the opposition to current flow. The
The conductivity of a material depends on several factors, including its atomic structure, temperature, and the
