Temperature dependence of the resistivity of gold, copper and silver. In general, electrical resistivity of metals increases with temperature. Electron–phonon At 20 °C, the resistivity of gold is approximately 2.44 × 10−8 ohm-m and steadily rises with increasing temperature. The temperature coefficient of a substance They assume from the outset, however, the existence of a temperature- independent residual resistance at very low temperatures. The interactions introduced by Figure 4 suggests that such temperatures may be very low indeed. The functions G, and Gq are useful in extrapolating high- temperature data to still higher The “alpha” (α) constant is known as the temperature coefficient of resistance and symbolizes the resistance change factor per Gold, Element, 0.003715. Since the electrical resistance of a conductor such as a copper wire is dependent upon collisional proccesses within Or, expressed in terms of the resistance at some standard temperature from a reference table: Gold, 3.4, Aluminum, 3.9.

For most conductors, resistivity increases with rising temperature. At 20 °C, the resistivity of gold is approximately 2.44 × 10 −8 ohm-m and steadily rises with increasing temperature. The temperature coefficient of a substance measures the amount of increase in the resistance of a 1 ohm sample of the conductor per degree rise in temperature (in Celsius).
