Electron scattering from the three-nucleon bound state with two- and three-body disintegration is described. The description uses the purely nucleonic charge-dependent CD-Bonn potential and its coupled-channel extension CD-Bonn+{delta}. Exact solutions of three-particle equations are employed for the initial and final states of the reactions. The current has one-baryon and two-baryon contributions and couples nucleonic with {delta}-isobar channels. {delta}-isobar effects on the observables are isolated. The {delta}-isobar excitation yields an effective three-nucleon force and effective two- and three-nucleon currents beside other {delta}-isobar effects; they are mutually consistent.
