what will happen if instead of neutral we use earth wire as
return conductor?if we can use ,then why we are not using in
our day to day appliances?please justify the answer

Answer Posted / ranadhir

If we use earthwire instead of neutral what will happen ??
Step potential appear between the feet ,may be around 5volt & a very small current ( mA ) will flow that human body may not feel.
Now in case of fault, fault current will flow to earth & human body standing on floor experience a shock because of rise of step voltage.
So in this case step & touch voltage is dangerous for survival.

I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
