  It is observed that the inductive and capacitive features of the memristor
reflect (and are a quintessence of) such features of any resistor. The very
presence of the voltage and current state variables, associated by their
electrodynamics sense with electrical and magnetic fields, in the resistive
characteristic v = f(i), forces any resister to accumulate some magnetic and
electrostatic fields and energies around itself, i.e. L and C elements are
always present. From the circuit-theoretic point of view, the role of the
memristor is seen, first of all, in the elimination of the use of a unique
v(i). This makes circuits with hysteresis characteristics relevant, and also
suggests that the concept of memristor should influence the basic problem of
definition of nonlinearity. Since the memristor mainly originates from the
resistor, it was found necessary to overview some unusual cases of resistive
circuits. The present opinion is that the framework of basic circuit theory and
its connection with applications should be logically expanded in order to
naturally include the new element.
