Answer Posted / j@ru ( sati)
as we know from R =pl\A bigger the size of area lesser the
resistance of conductor...so b using this concept earth pin
provides less resistance to leakage current compared to
other two pin hence leakage current by pass to earth without
damagng appliances..
thats all thank you
