The Hamiltonian for the subsystem consisting of the interacting particles is shown to be form invariant under gauge transformation, but numerically dependent on the choice of gauge. The energy, which is numerically the same in all gauges, is obtained by subtracting the scalar potential of the time\u2010dependent radiation field from the Hamiltonian. The time rate of change of the energy of the particles is equal to the Joule power, which is the power lost by the field, so that energy of the entire isolated system consisting of particles and radiation field is conserved.
