  We study the charged slowly rotating black holes in the Einstein-Maxwell
theory in the large dimensions. By using the 1/D expansion in the near region
of the black hole we obtain the effective equations for the charged slowly
rotating black holes. The effective equations describe the charged black ring,
the charged slowly rotating Myers-Perry black hole and the charged slowly
boosted black string as stationary solutions. By embedding the solution of the
effective equations into the flat spacetime background in the ring coordinate
we obtain the charged black ring solution at large D analytically. We find that
the charge lowers the angular momentum of the black ring due to the regular
condition on the solution. By the perturbation analysis of the effective
equations, we obtain the quasinormal modes of the charge perturbation and the
gravitational perturbation analytically. Like the neutral case the charged thin
black ring suffers from the Gregory-Laflamme-like instability under
non-axisymmetric perturbations, but the charge helps weaken the instability.
Besides, we find that the large D analysis always respect the cosmic
censorship.
