That is simply untrue.In theory if you had 4 lamps of equal wattage wired in a ring, there will be no current flow in the cable between the second and third lamp.
Even under these conditions.Only if the bulbs were evenly spaced, exactly the same construction and cable length on both sides.
If the ring is perfectly symetrical and has an even number of lamps (e.g. there is no lamp at the midpoint) then the voltages at the lamps either side of the midpoint would be equal. Therefore there should be no current flowing in the cable between them.Even under these conditions.Only if the bulbs were evenly spaced, exactly the same construction and cable length on both sides.
Ahh. Hmmm.
