Through the lamps on yellow and blue phases
if the lamps are all the same rating, theoretically all of current A would travel down this route and the system would be balanced and N current would be zero.
imagine though the lamp on blue phase blew and became open circuit.
a portion of the current would then go down the N, some from the lamp on red phase, some from lamp on yellow phase.
