Answer
An electric dipole is a molecule or an object that is electrically polarized, such that the "center of positive charge" is shifted from the center of negative charge. Such an object generally has no net charge. A water molecule, which is a dipole, is shown in Figure 22.15. Note that the center of positive charge (between the H atoms) is higher on the page than the center of negative charge.
