Understanding Electric Resistivity
Electric resistivity (ρ) is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current.
The SI unit for electric resistivity is the Ohm meter (Ω·m).
| Material | Resistivity (Ω·m) | Resistivity (µΩ·cm) |
|---|---|---|
| Silver | 1.59 × 10-8 | 1.59 |
| Copper | 1.68 × 10-8 | 1.68 |
| Gold | 2.44 × 10-8 | 2.44 |
| Aluminum | 2.65 × 10-8 | 2.65 |
| Nichrome (NiCr alloy) | 1.10 × 10-6 | 110 |
| Carbon (graphite) | 2.5 × 10-6 to 5.0 × 10-6 | 250 – 500 |
| Silicon (pure) | ~2300 | ~2.3 × 108 |
| Glass | 1010 to 1014 | 1015 to 1019 |
