We give a comparative description of monopole and electrically chargedspherically symmetric dust thin shells. Herewith we consider two of the mostinteresting configurations: the hollow shell and shell, surrounding a body withopposite charge. The classification of shells in accordance with the types ofblack holes and traversable wormholes is constructed. The theorems for theparameters of turning points are proved. Also for atomlike configurations theeffects of screening (electrical case) and amplification (monopole case) of theinternal mass by shell charge are studied. Finally, one considers the quantumaspects; herewith, exact solutions of wave equations and bound states spectraare found.Comment: 18 pages, REVTeX 3.
