SPECIFIC RESISTANCE (K)

The Specific Resistance (K) of a material is the resistance offered by a wire of this material which is one foot long with a diameter of one MIL.
Material  "K" Material "K"
Brass 43.0 Aluminum 17.0
Constantan 295 Monel 253
Copper 10.8 Nichrome 600
German Silver 18 % 200 Nickel 947

  • The resistance of a wire is directly proportional to the specific resistance of the material.
  • "K" = Specific Resistance
