  In this paper, we investigate the effects of electromagnetic field on the
isotropic spherical gravastar models in metric $f(R,T)$ gravity. For this
purpose, we have explored singularity-free exact models of relativistic spheres
with a specific equation of state. After considering Reissner Nordstr\"{o}m
spacetime as an exterior region, the interior charged manifold is matched at
the junction interface. Several viable realistic characteristics of the
spherical gravastar model are studied in the presence of electromagnetic field
through graphical representations. It is concluded that the electric charge has
a substantial role in the modeling of proper length, energy contents, entropy
and equation of state parameter of the stellar system. We have also explored
the stable regions of the charged gravastar structures.
