About the electric resistivity converter
Electric resistivity (ρ) is an intrinsic material property describing how strongly the material resists current flow, independent of geometry. The SI unit is the ohm-meter (Ω·m). Copper sits near 1.7 × 10⁻⁸ Ω·m, while glass exceeds 10¹¹ Ω·m. Materials scientists, semiconductor engineers, and geophysicists all use resistivity to characterize conductors, insulators, and rock layers.
Frequently asked questions
-
How do you compute resistance from resistivity?
R = ρ × L / A, where L is the conductor length and A its cross-sectional area.
-
What is the resistivity of copper?
About 1.68 × 10⁻⁸ Ω·m at 20 °C, which is why it is the standard wiring material.
