Answer Posted / tarun aggawal ymca
actually earth socket has large dia becouse when short ckt
occur the large current flow through this low resistance path
as R = P*l/a as area is large smaller is resistance and
excess will the current flow through it
also if the socket is small we have such a large current
flow throw it and a large heat is produced which will damage
the pin because if area is small heat per area is large and
pin get melted as like a fuse
