What is the resistivity of a conductor?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Conductors have very low resistivity values, typically in the range of 10⁻⁸ to 10⁻⁶ Ω·m. Common examples include:
- Silver: 1.59 × 10⁻⁸ Ω·m (best conductor)
- Copper: 1.68 × 10⁻⁸ Ω·m
- Gold: 2.44 × 10⁻⁸ Ω·m
- Aluminum: 2.82 × 10⁻⁸ Ω·m
The lower the resistivity, the better the material conducts electricity.
