What materials have high resistivity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Materials with high resistivity are typically insulators:
- Rubber: ~10¹³ Ω·m
- Glass: ~10¹⁰ to 10¹⁴ Ω·m
- Teflon: ~10²³ Ω·m
- uartz: ~10¹⁶ Ω·m
- Air/vacuum: ~10¹⁶ Ω·m
- Pure water: ~2.5 × 10⁵ Ω·m
These materials are used in electrical insulation, protective coatings, and situations where current flow must be prevented.
