{wiki=Electrical_resistivity_and_conductivity}
Electrical resistivity and conductivity are two fundamental properties of materials related to their ability to conduct electric current. \#\#\# Electrical Resistivity - **Definition**: Electrical resistivity (often denoted as \\( \\rho \\)) is a measure of how strongly a material opposes the flow of electric current. It quantifies how much resistance is encountered when an electric charge moves through a material. - **Units**: The SI unit of resistivity is ohm-meter (Ω·m).
