Electrical conductivity


 

Electrical conductivity is a measure of how well a material accommodates the transport of electric charge. Its SI derived unit is the siemens per metre, (A2s3m-3kg-1) (named after Werner von Siemens).

Some typical electrical conductivities

  • Silver: 63 · 106 S/m (630,000,000,000 µS/cm; highest electrical conductivity of any metal)
  • Sea water: 5 S/m (50,000 µS/cm)
  • Drinking water: 0.005 – 0.05 S/m (50-500 µS/cm)
  • Ultra pure water: 5.5 · 10-6 S/m (0.055 µS/cm)
