  The response of electromagnetic (EM) fields that are produced in non-central
heavy-ion collisions to electromagnetically charged quark gluon plasma can be
understood in terms of charge transport and charge diffusion in the hot QCD
medium. This article presents a perspective on these processes by investigating
the temperature behavior of the related transport coefficients, {\it viz.}
electrical conductivity and the charge diffusion coefficients along with charge
susceptibility. In the process of estimating them, thermal relaxation times for
quarks and gluons have been determined first. These transport coefficients have
been studied by solving the relativistic transport equation in the
Chapman-Enskog method. For the analysis, $2\rightarrow 2$, quark-quark,
quark-gluon and gluon-gluon scattering processes are taken into account along
with an effective description of hot QCD Equations of state (EOSs) in terms of
temperature dependent effective fugacities of quasi-quarks (anti-quarks) and
quasi-gluons. Both improved perturbative hot QCD EOSs at high temperature and a
lattice QCD EOS are included for the analysis. The hot QCD medium effects
entering through the quasi-particle momentum distributions along with an
effective coupling, are seen to have significant impact on the temperature
behavior of these transport parameters along with the thermal relaxation times
for the quasi-gluons and quasi-quarks
