  The inclusion of two-body exchange currents in the constituent quark model
leads to several new relations between the electromagnetic form factors of the
nucleon and Delta(1232). These are:(i) the neutron charge form factor can be
expressed as the difference between proton and Delta+ charge form factors, and
(ii) the N->Delta charge quadrupole (C2) transition form factor is connected to
the charge monopole (C0) form factor of the neutron. The latter relation is
used to estimate the charge radius of constituent quarks. Furthermore, we find
that exchange currents do not modify the SU(6) relation between the magnetic
N->Delta and the magnetic neutron form factors. Consequently, after including
exchange currents, the C2/M1 ratio in the N->Delta transition can be expressed
as a ratio of the elastic charge and magnetic form factors of the neutron.
