Charge dependent directed flow is an important observable of electromagnetic fields in relativistic heavy-ion collisions. We demonstrate how the difference charge flows between protons and antiprotons sensitive to resistivity, inverse quark-gluon plasma's electric conductivity, over different collision centralities. Our model numerically solves 3+1D resistive magneto-hydrodynamic (RRMHD) equations, assuming conductivity be a scalar. For this work, we focus on symmetric Au + collisions at top RHIC energy $\sqrt{s}=200$ GeV. illustrate time evolution our connect that results. results highlight importance modeling for observables
