The electric conductivity of a hadron gas is calculated within the hadronic transport
approach SMASH (Simulating Many Accelerated Strongly-interacting Hadrons). Microscopic
non-equilibrium models are well suited to calculate transport coefficitents that
synthesize the information on the many-particle dynamics. The temperature dependence of
the electric conductivity is extracted using the Green-Kubo formalism for
$T\sim 100-200~\mathrm{MeV}$. The results for the electric conductivity show good agreement
compared to analytic results from literature [Phys.Rev.D 93, 096012 (2016)] for systems
with small number of particle species and simple interactions. Furthermore, the influence of a
finite lifetime of resonances on the electric conductivity is investigated. After validating
the approuch results for the electric conductivity of a more realistic hadron gas including more
particle species are presented.
