We have calculated the conductivities of the 3d, 4d, and 5d transition metals by using a quasiclassical Boltzmann approach which utilizes self-consistent energy bands. Electron scattering is characterized by a constant scattering strength which treats all sources of resistivity on an equal footing. This results in a single parameter theory with which we are able to reproduce, qualitatively, trends and anomalies in conductivity throughout the transition metal series. By the choice of an appropriate scattering strength at each temperature, we are able to reproduce these trends over the experimentally observable temperature range of 10-1000 K. In particular, the well known dip in conductivity at the middle of the series, especially pronounced for Mn, is understood in terms of the host electronic structure.
