The residual resitivity of copper per atomic percent of interstitial atoms is computed in several different models. It is found that the contributions from the defect itself and from the associated lattice strain are of comparable magnitude and that the interference between them tends to reduce the...

Manganin (which is made of copper, manganese and nickel), for example, has α close to zero (to three digits on the scale in Table 2), and so its resistivity varies only slightly with temperature. This is useful for making a temperature-independent resistance standard, for example. Table ...
As an example, copper is a good conductor as it provides a low level of resistivity, its cost is not too high, and it also provides other physical characteristics that are useful in many electrical and electronic applications. The resistivity of copper is around 1.7 x 10-8ohm metre (or 17...
Resistivity of copper is 1.7 * 10^(-8) ohm-m. You measure the resistance of a 1-m long wire with a 1 mm radius to be 95,000 \Omega. What is its resistivity? What is the resistance of a 1.30 m long copper wire that ...
Capacity of the material to pass electric charge is known as electrical conductivity. Electrical resistivity is the reciprocal of electrical conductivity. Ohm metre is the unit of resistivity. Resistivity of conductors are poor while the resistivity of

the top part of the core becomes thermally convective. When the heat extracted from the core through the CMB is less than the adiabatic heat flow, the top part of the core is thermally conductive and thermal convection is negligible. In this case, compositional convection that arises from the...
