Answer / sajib

Only one of the terminals is evident in the earth
resistance. In order to find the second terminal we should
recourse to its definition: Earth Resistance is the
resistance existing between the electrically accessible part
of a buried electrode and another point of the earth, which
is far away

The resistance of the electrode has the
following components:
(A) the resistance of the metal and that of the connection
to it.
(B) the contact resistance of the surrounding earth to the
electrode.
(C) the resistance in the surrounding earth to current flow
or earth
resistivity which is often the most significant factor.
