Residual-resistance ratio
ID: residual-resistance-ratio
The residual-resistance ratio (RRR) is a measure used primarily in the field of superconductivity and materials science to assess the purity and quality of conductive materials, particularly metals. It is defined as the ratio of the resistivity of a material at room temperature (or a higher temperature) to the residual resistivity of that material as it approaches absolute zero temperature.
