Is electric conductivity homogenous or heterogenous?

Answer 1

Electric conductivity can be both homogeneous and heterogeneous, depending on the material and its structure. In a homogeneous material, such as a pure metal, conductivity is uniform throughout. In contrast, heterogeneous materials, like composites or mixtures, can exhibit varying conductivity due to differences in composition or structural properties. Thus, the conductivity's nature depends on the specific material being examined.
