Answer / m.srinivasa reddy
at the time of putting the plug top in plug point first earth pin touches the earth pin.any leakage is there then it will goes to the earth. then it will be safety for us and we can save human.

Answer / kundanmalani1990
they are depend to the r=row L\A mean the resister are
increase so the cross area are the decrees mean resi are
inversely proportional to the cross section of area ... and
so the resi are to the high so the plug point is the bigger
to compere to the two pin

Answer / dhivyabharathi
The earth pin has to send fault current to earth.so, the
resistance of that path should be low.to get low resitance,
cross sectional area should be more. it can be understood
from R=pl/A.so the cross sectional area of tat pin should be
high.

Answer / siva
I. we can differancate the Earth pin form other pins then
in Earn Pin Is Bigger to avoid melting during the short
circuit current ,overheat , then human safety

Answer / akshita
R= raw*L/A
so resistance is directly proportional to the length and resistivity.
human body resistance is law and always current choose law resistance4 path that's for earth pin is big for choosing a law resistance path for the current
