If the material has resistivity (Ω-cm) in the range of 10⁵ to 10⁹, then the material is termed as a/an?

If the material has resistivity (Ω-cm) in the range of 10⁵ to 10⁹, then the material is termed as a/an?

Explanation

Resistivity is a measure of how strongly a material opposes the flow of electric current.

Here's a general classification based on resistivity (in Ω-cm):

Material TypeResistivity Range (Ω-cm)
Conductors10−6 10^{-6}to 10−2
Semiconductors10−210^{-2} to 10^4
Insulators10510^5to  to 10^9101810^{18}
Superconductors≈ 0 (below critical temperature)
So, if a material has resistivity between 

 and 10 ^9 Ω-cm, it is classified as an insulator because it resists the flow of electric current very strongly.
