| Abstract: | A set of linear relationships between resistance and thermoelectric properties caused by impurities in metals have been derived from Matthiessen's rule and the Mott theory. These are the linear relationships between temperature coefficient of resistance and thermoelectric power or motive force, the change in resistance ratio and impurity concentration, and the change in temperature coefficient of resistance and impurity concentration etc. In terms of these linear relationships we have interpreted the empirical formulae and experimental results of platinum containing impurities in detail. |
