Answer / vikas jauhari

I am fully agree with Mr. RD Dadhich....

This is well explained in BS1363...

so don't forget there is no connection with cross sectional
area for low resistive path

Answer / rajesh.v

1.it will
provide high
conductivity...
2.it is very
useful for
identify the
sequence
terminal as
earth, phase,
neutral...
3.the earth
point are give
most support to
hold with
socket...

Answer / neha

as we know that the area of cross section is inversely proportional to the area or R=rho(l/a)....so to decrease the resistance there is a large hole of earth in plug point as it is connected to zero potential (earth) for safety purpose

Answer / dinesh

1) Resistivity is less
2) It will not get n the phase or neutral hole
3) It will be easily go into the hole
4) The equipment is first earthed & then it is charged
because the length og earth plug is more than others
5) Look wise it looks good.

Answer / n.d.mahesh

usually all the metal body equipments have the earth for
example washing machine, refrigerator ,oven.we cannot see
the earth pin in the t.v,this is for the protection that is
the metals are good conduactors and when human intend to
touch then it causes shock,if there is any leakage in the
circuit.so to prevent this we are using the earth.

Answer / rajesh mishra

as we know R is pro to row*L/a...if "a" is larger then r is
small..so the resist is small and it easily pass the s.c
current through it......thts why the earth hole size is
biggest in plug pt.

Answer / kundan malani

R = row L/A.......(1)
r is increase so the a is decrease so the depend to this
equation 1

Answer / t.manivannan

because of manufacturer defect....hehehe

Answer / dindo

Earth is a big conductor if we are talking about the
conductivity so the theory is the bigger the size the
smaller the resistance so the earth itself serve as a
conducting path of the resistance to secure the lives and
safety of the properties if in case there is incidental and
transient fault of the power systems.

Answer / saleem.d

What is this my dear friends ?
lot of people will give same answer by using different
words.I think who ever was given relation of Resistance and
Area that is the correct answer.

ANY COMMENTS ???????
