The Weber potential U is limited to relative velocities between charges V less than\(\sqrt {2c} \) and fails when V→2c. If the relative velocity of action between charges is c, then U equals the root-mean-square average of the retarded and advanced Coulomb potential. But, if the velocity of action c is absolute, in agreement with light propagation, then V→2c must be admissible. A potential W is proposed, involving absolute individual charge velocities, that permits V→2c and yields W=U for small velocities.
