Question
Why used in layer by layer charcoal and salt used in earth 
pits.
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
The layer of charcoal and salt helps to maintain low
resistance for earth fault currents.Because of ionic
behaviour of salt and charcoal they will maintain moisture
content around the earht pit.

Answer
# 2
its because Salts are ionic compounds composed of cations
(positively charged ions) and anions (negative ions) so
that the product is electrically neutral (without a net
charge), and these are the electro-chemical properties that
make them suitable for buffering of electricity from the
copper rod to earth's soil, they work best when they are
dissolved in water becouse that is when the ions are
produced.The layer of charcoal and salt helps to maintain
low
resistance for earth fault currents.Because of ionic
behaviour of salt and charcoal they will maintain moisture
content around the earht pit.

Answer
# 4
because charcoal is a good conductor of electricity and also
charcoal and salt helps to maintain the low resistance path
for fault current.

Answer
# 5
charcoal is maitain the low resistance and high
conductivity.
salt is desolved in water the possitive ions abserved by
charcoal and released so the earth resistance maintain
properly.
 
Is This Answer Correct ?    7 Yes 2 No

Answer
# 6
by usage of charcoal and salt in earthing we can reduce the
resistance and also it will give moisture content for a long
time.so it early discharges the faulty current into earth.

Answer
# 7
Charcoal is porous - locks in moisture that salt attracts
and dissolves in - ionised solution is kept on large
reaction area that charcoal pores provide. Such locked in
material is prevented from drying up easily.
