Question

what happened when we touch neutral line voltage wire​

Answer 1

Answer:

its gives a huge shock making us paralyzed

Answer 2

Your answer is:

When load is connected to the plug point the neutral may not always be at zero potential. Some voltage between earth and neutral(at a high potential) can give you a shock. ... If this becomes high of about 50V or more and you touch neutral you will get a shock. It is common that wiring is done incorrectly.
