Popis:	We utilize a light-front relativistic quark model to predict the 3q core contribution to the electroexcitation amplitudes for the Δ(1232)P33, N(1440)P11, N(1520)D13, and N(1535)S11 up to Q2 = 12 GeV2. The parameters of the model have been specified via description of the nucleon electromagnetic form factors in the approach that combines 3q and pion-cloud contributions in the light-front dynamics.
