A solvable quantum LC circuit with charge discreteness is studied. Two discrete spectral branches are obtained: i) the normal branch corresponding to a charged capacitor with integer effective charge k=qen ( qe elementary charge, n integer) and ii) the anomalous branch where the energy is related to non-integer effective charge k=qe(n-x) in the capacitor. For usual mesoscopics data like quantum point contact we found .
