I do wonder why current is present in neutral wire?i check
single phase lead current feeding air conditioner...on its
phase its current was 10A while same was 10A in neutral...as
we know in neutral voltage is zero so if voltage is zero
then how current appears on amp meter?
my second observation is (just imagination)when I touch
phase wire it give me shock but when i touch neutral nothing
happens although as above its carrying current(amps)
third but with same logic...as in simple Alternate current
sine curve there is + and there is negative peak.means every
time phase changing so how come every time same phase and
same neutral stand
(pardon for english mistakes)

Answer / puneeth kumar
In neutral current should flow, because it is return path. It
is not giving shock or while checking in tester it will not
glow, because current always choose the least path and neutral
is earthed and our body as about 1000ohms (as per IEEE 80).
In neutral always voltage will be zero only, since it will
connected to ground in star point of transformer. Positive and
negative waves will be appearing in phase only.
Check in 2 phase, you will get 2 waves.
