We calculate the charge form factors and the rms charge radii of ${}_{}{}^3{}_{}{}^{}\mathrm{H}$ and ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ using the wave functions generated from the solutions of the Faddeev equations in momentum space with the new Bonn one-boson-exchange momentum space potential. For the charge radii, we obtain, $r_c$${(}^3$H)=1.72 fm and $r_c$${(}^3$He)=1.89 fm, which are in excellent agreement with the experimental data. However, our results for the trinucleon charge form factors in the impulse approximation indicate no improvement with regard to the experimental situation.
