The *specific
resistance* of a conductor is the resistance across two opposite faces of a
1 cm cube made of the conductor material. The *specific conductance* (k) of a solute is the reciprocal of the
specific resistance, *i.e.,*

_{}

Thus the conductance of a given solution (C) is given by,

The conduction
of all the ions produced by 1 g equivalent of an electrolyte at any particular
concentration can be evaluated by imagining two large parallel electrodes, 1 cm
apart, and the whole of the solution placed between them. The conductivity of
the system is called the *equivalent conductance* (L).

If 1 g
equivalent of the electrolyte is dissolved in (v) ml of solution; then it follows
that this will cover (v) cm^{2}
of electrode area. It follows that in the above equation (a) becomes (v) and
(l) is unity and
