Sähköjohtavuutena
Sähköjohtavuutena, also known as electrical conductivity, is a measure of a material's ability to conduct electric current. It is defined as the reciprocal of electrical resistivity and is typically expressed in units of siemens per meter (S/m). Materials with high electrical conductivity, such as metals like copper and silver, allow electric current to flow easily. Conversely, materials with low electrical conductivity, like insulators such as rubber and glass, impede the flow of electric current.
The electrical conductivity of a material depends on several factors, including its composition, temperature, and the
Electrical conductivity is a crucial property in various applications, including electronics, power transmission, and heat management.
