Conductors have low resistivities in the range of 10-8 Ωm to 10-6 Ωm. Metals are good conductors. Conductors are objects or types of material that allows the flow of charge in one or more directions, and a result, the resistance offered against the flow of charge will be less.

Conductors
In the range of resistivities from 10-8 Ωm to 10-6 Ωm, the materials that fall into this category are conductors. Conductors have low resistance and allow the flow of electric current with ease. Here's why conductors have resistivities in this range:
Free Electron Density:
- Conductors have a high density of free electrons which are responsible for the conduction of electricity. These free electrons move freely within the material, allowing for a high level of conductivity.
Band Structure:
- In conductors, the conduction band and valence band overlap, leading to a large number of free electrons available for conduction. This results in a low resistivity value.
Examples of Conductors:
- Examples of conductors include metals such as copper, silver, and aluminum. These materials have resistivities in the range mentioned above and are commonly used in electrical wiring and electronic components.
In summary, materials with resistivities in the range of 10-8 Ωm to 10-6 Ωm belong to the category of conductors due to their high density of free electrons and overlapping band structure that facilitate easy flow of electric current.
