Residual-resistivity ratio (also known as Residual-resistance ratio or just RRR) is usually defined as the ratio of the resistivity of a material at room temperature and at 0 K. Of course, 0 K can never be reached in practice so some estimation is usually made. Since the RRR can vary quite strongly for a single material … See more Usually at "warm" temperatures the resistivity of a metal varies linearly with temperature. That is, a plot of the resistivity as a function of temperature is a straight line. If this straight line were extrapolated all the … See more • The RRR of copper wire is generally ~ 40–50 when used for telephone lines, etc. See more • For superconducting materials, RRR is calculated differently because ρ is always exactly 0 below the critical temperature, Tc, which may be significantly above 0 K. In this case the RRR is calculated using the ρ from just above the superconducting transition … See more • Ashcroft, Neil W.; Mermin, N. David (1976). Solid State Physics. Holt, Rinehart and Winston.
