a Schematic of the fundamental circuit elements: resistor, capacitor, inductor and memristor. b, c The plots show the applied voltage (blue) and resulting current (green) as a function of time t for a typical memristor. In b the applied voltage is v0sin(ω0t) and the resistance ratio is Roff/Ron = 160. In c the applied voltage is ±v0sin 2(ω0t) and Roff/Ron = 380. The numbers 1–6 on the top plot in c indicate the successive waves in the applied voltage and label the corresponding loops in the i–v curves. The insets in the iv plots in b and c show that in these cases the charge is a single-valued function of the flux, as it must be in a memristor. Reproduced from ref. [32] with permission
