In the following table, the resistivity, r, is
given in the units "microohm-cm" where
R = rl/s
and R = resistance, in microohms,
l is the length in centimeters, and
s is the uniform cross section in square centimeters.
The data are from Smithsonian Physical Tables, Smithsonian
Institution Press, 1969.
| Metal | Resistivity, r |
| gold, 99.9 pure, 0 degrees C | 2.22 |
| silver, 99.98 pure, 18 degrees C | 1.63 |
| silver, electrolytic, 0 degrees C | 1.47 |
| copper, annealed, 20 degrees C | 1.72 |
| platinum, wire, 0 degrees C | 11.0 |
