Neutral is not used for power supply purpose as in phase..
every equipment runs only when the circuit is closed.. to
make the circuit close neutral is used.....

Answer / parag

neutral is a point which is always kept at ground potential
i.e 0 volts. it's used for the completion of a closed
circuit.again we know that in a sinusoidal ac voltage
waveform the voltage varies from -V to +V.hence it has to
cross through the 0 voltage level.hence neutral is
necessary.again for the occurence of any type of fault the
neutral serves as a path for the passage of the fault
current. in a balanced 3 phase system for suppose a
y-conncted network Ia+Ib+Ic=0.For an unbalanced 3 phase
fault we see that Ia+Ib+Ic=If....which is the fault current
and it flows throught the neutral..

Answer / ssk

Neutral Will allow us to complete the circuitry in case of
the system..
Also it acts as a ground 2 t negative charges..

Answer / sravani

neutral means it a zero potential .it is used to protect
the alternator.if fault exists to flow such high currnt to
the neutral

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
