Physics Question and answers already passed Physics ... - correct answer The Coulomb one, in which the divergence of the vector potential is set to zero, is often used when sources are not present. Within the Lorentz one, the divergence of the vector potential plus the product of one over c and the time derivative of the scalar potential is zero. Transformations given this name include, for instance, the addition of the gradient of a scalar function to the vector potential. For 10 point...
