Electrical conductivity of copper.

Copper is the standard by which electrical materials are judged, and conductivity is expressed as a relative measurement for copper.

IACS is an abbreviation for International Copper Annealing Standard and the number preceding “IACS” is the percentage of the material’s conductivity relative to copper, which is considered 100% conductive. This does not mean that copper has no resistance (100% conductive in an absolute sense), but rather that it is the standard by which other materials are measured. The higher the% IACS, the more conductive the material. This standard refers to pure “standard” copper having a resistivity of 1.7241 micrometers at 20 ° C.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
