When a voltage potential is placed across a wire, the
number of electrons that will flow will depend on the
degree of freedom of electrons in the conducting wire. The
ability of the wire to conduct is called conductance,
but this property of the wire is normally considered in
terms of how it restricts the flow of electrons, that
is its resistance. Resistance is measured in ohms (W).
