i work as a technician at a private company.. i used to take
amp reading for certain appliances such as air con.. the
problem is when i clamp the neutral, wire there is a current
reading.. from my understanding for single phase system
neutral should not have current unless if the circuit is not
complete.. yet the air con still work

Answer Posted / pillay
your understanding is wrong or if not
incomplete.
In any single phase circuit the neutral
is the return path
for the circuit. That means the current that
flows into the phase comes out through the neutral
Even in 3 PH balanced load you will see the
same individual ph current in the neutral but
you will see no current in the main neutral,
cos at the neutral bar the individual neutral
current had balanced up through the other phases.
