Answer / arvind

because load in practical cannot be balanced, so because of
that the uneven current flows in the circuit means three
phase,neutral tries to balance the load.

Answer / nanjunda

Current flows in neutral also but in threephase circuits
the neutral of transformer is earthed, hence reference
voltage from ground to the neutral always showing zero or
upto 7 volts. hence even if we touch the live neutral wire
with bare foot also we wont experience shock.
