Residual resistivity
WebNational Center for Biotechnology Information The electrical resistivity of most materials changes with temperature. If the temperature T does not vary too much, a linear approximation is typically used: where is called the temperature coefficient of resistivity, is a fixed reference temperature (usually room temperature), and is the resistivity at temperature . The parameter is an empirical parameter fitted from measurement data, equal to 1/ . Because the linear approximation is only an approxim…
