Electrical transport properties viz. electrical resistivity and thermal conductivity of Ni-Cr binary alloys are determined by the recognized single parametric potential model in a wide range of Cr concentration. In this work, screening functions of Ichimaru and Utsumi, Farid et al. and Sarkar et al. are employed along with the Hartree and Taylor functions to study the relative influence of the exchange and correlation effect. The Ni-Cr liquid alloys are studied as afunction of their composition at three different temperatures (T=800K, 1000K, 1200K). The present finding of electrical resistivity agrees within 2-12 percent with experimental findings when the H dielectric function is employed.
