In your diagram, the + terminals would all be connected to the A arms. Assuming a half wave spacing of the dipole feedpoints, the EM fields can cancel parallel to the antenna elements, thethen add up to a stronger waveform propagating in the perpendicular direction.
Assuming all the voltage sources are isolated, the EM field will simply keep "adding up" right to left; and the EM coupling between dipoles might generate a much higher voltage differential across the entire array than within any individual dipole.
