sähköjohtamisen
Sähköjohtaminen, also known as electrical conductivity, is a fundamental property of materials that describes their ability to conduct electric current. It is the inverse of electrical resistivity. Materials with high electrical conductivity allow electric charge to flow easily through them, while materials with low conductivity resist the flow of charge.
Metals, such as copper, silver, and gold, are excellent electrical conductors due to the presence of free
The phenomenon of electrical conductivity is crucial in numerous technological applications, including electrical wiring, electronic components,
