Testing extra dimensions at low-energies may lead to interesting effects. Inthis work a test point charge is taken to move uniformly in the 3-dimensionalsubspace of a (3+$n$)-brane embedded in a (3+$n$+1)-space with $n$ compact andone warped infinite spatial extra dimensions. We found that the electromagneticpotentials of the point charge match standard Liennard-Wiechert's at largedistances but differ from them close to it. These are finite at the position ofthe charge and produce finite self-energies. We also studied a localizedHydrogen atom and take the deviation from the standard Coulomb potential as aperturbation. This produces a Lamb shift that is compared with knownexperimental data to set bounds for the parameter of the model. This workprovides details and extends results reported in a previous Letter.Comment: Manuscript (LaTeX) and 2 figure files (eps format) used by the  manuscript LaTeX fil
