Electrodisintegration of the three-nucleon bound state with two-body final states is described. The describtion uses nucleon degrees of freedom extended to include the excitation of a single nucleon to a Delta isobar. The baryonic interaction and the electromagnetic current couple nucleonic states and states with a Delta isobar. Exact solutions of three-particle scattering equations are employed for the initial and final states of the reactions: due to the excitation of the Delta isobar an effective three-nucleon force is included. The current has one-baryon and two-baryon contributions. Theoretical predictions for the reactions with selected kinematic specifications are given. The role of the Delta isobar in the description of the considered processes is discussed and its effect on observables is quantitavely isolated.
