The electron-phonon contribution to the normal-state resistivity, \ensuremath{\rho}(T), has been calculated for the following conventional and oxide superconductors: Nb, V, VN, ${\mathrm{Ba}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{K}}_{\mathit{x}}$${\mathrm{BiO}}_{3}$, and ${\mathrm{Nd}}_{1.85}$${\mathrm{Ce}}_{0.15}$${\mathrm{CuO}}_{4}$ (NCCO). The resistivity formula developed from the Boltzmann equation by Ziman and Allen is used, incorporating measured physical constants. The calculations are novel in that they incorporate the electron-phonon spectral function, ${\mathrm{\ensuremath{\alpha}}}^{2}$F(\ensuremath{\omega}), for each material as obtained from superconducting tunneling measurements, the same function that yields the superconducting transition temperature ${\mathit{T}}_{\mathit{c}}$. New tunneling and transport data are presented for VN. Fits to the experimental \ensuremath{\rho}(T) are obtained over a wide temperature range with only two parameters: the plasma frequency ${\mathrm{\ensuremath{\omega}}}_{\mathit{p}}$, which is in good agreement with independent measurements and a saturation resistivity, ${\mathrm{\ensuremath{\rho}}}_{\mathit{s}}$, which manifests itself at high temperatures. We find that the T-dependent normal state \ensuremath{\rho}(T) is completely accounted for by phonon scattering in all materials except NCCO, where an additional electron-electron scattering term appears to be present. Apart from developing a consistent description of superconductivity and normal-state transport, several important issues are raised by the present work including indications of a conventional Fermi-liquid normal state in NCCO, insight into the importance of the shape of the Fermi surface in determining \ensuremath{\rho}(T), and the role of high-energy optical phonons in oxide and nitride superconductors.
