Frequently Asked Questions

What is electric resistivity?

Electric resistivity is a measure of how strongly a material opposes the flow of electric current. It’s the reciprocal of conductivity and is measured in ohm-meters (Ω·m) in the SI system.

When would I use circular mil ohm/foot?

This unit is commonly used in wire and cable specifications, particularly in North America. It combines the wire’s cross-sectional area (in circular mils) with its resistance per unit length.

What’s the difference between ohm-cm and microhm-cm?

1 ohm-cm = 1,000,000 microhm-cm. Microhm-cm is used for highly conductive materials like metals, while ohm-cm is used for semiconductors and resistive materials.

What are typical resistivity values?

Copper: ~1.68×10⁻⁸ Ω·m; Silicon: ~2.3×10³ Ω·m; Glass: ~10¹⁰-10¹⁴ Ω·m; PTFE: ~10²³ Ω·m
