Electromagnetic form factors of a variety of hadrons are calculated, using Wilson fermions with SU(3) color on a quenched 24 × 12 × 12 × 24 lattice at β = 5.9, from three-point correlation functions constructed using the lattice conserved vector current. With small errors, the computed pion form factor is consistent with the monopole form suggested by the vector dominance model. Differences in charge radii between hadrons, and the electric and magnetic form factors of nucleons depend on the quark mass in a physically reasonable way.
