> Chua in his 1971 paper identified a theoretical symmetry between the non-linear #resistor (voltage vs. current), non-linear #capacitor (voltage vs. charge), and non-linear #inductor (magnetic flux linkage vs. current). From this #symmetry he inferred the characteristics of a fourth fundamental non-linear circuit element, linking magnetic flux and charge, which he called the #memristor. In contrast to a linear (or non-linear) resistor the memristor has a dynamic relationship between current and voltage including a #memory of past voltages or currents.
