A model potential depending on an effective core radius but otherwise parameter free is used for the comparative study of electrical resistivity of d and f-shell liquid metals. In the present paper electrical resistivity of d and f-shell liquid metals have been calculated using Ziman's formula, Ziman's formula modified and used by Khajil and Tomak and t-matrix formulation given by Evans and Evans et al. Previously no one have reported such comparative study using pseudopotentials. In the electrical resistivity calculations we have used structure factor derived through charge hard sphere approximation. The beauty of this approximation is that it needs pseudopotential form factor for the calculation of structure factor. So this gives the better explanation of structure factor than any other approximations. From present investigations it is found that t-matrix formulation results are excellently agrees with the experimental findings. A successful application is an evidence our potential to predict wide class of physical properties of d and f-shell metals.
