If the material has resistivity (Ω-cm) in the range of 10⁵ to 10⁹, then the material is termed as a/an?
Answer: Insulator
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 Type | Resistivity Range (Ω-cm) |
|---|---|
| Conductors | to |
| Semiconductors | to |
| Insulators | to to 10^9 |
| Superconductors | ≈ 0 (below critical temperature) |
10^5 and 10 ^9 Ω-cm, it is classified as an insulator because it resists the flow of electric current very strongly.
