Copper Resistivity

Bulk Properties of Copper Density and Resistivity

the resistivity of copper and aluminium Resistivity is a measure of how hard it is to get an electric current to flow in any material Copper is an excellent conductor so it has a LOW resistivity Adding the resistivity term gives R = ρ L A ρ is the constant of proportionality again so
