What is the electrical resistivity of Copper? Correct Answer 1.68 * 10-8

The electrical resistivity of Copper is 1.68 * 10-8. The electrical resistivity of Silver, Aluminum, and Zinc is 1.59 * 10-8, 2.65 * 10-8, and 5.9 * 10-8 in that order. The electrical resistivity is generally measured at 20oC.
