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(Ļ0t) and the resistance ratio is Roff/Ronā=ā160. In c the applied voltage is ±v0sin 2(Ļ0t) and Roff/Ronā=ā380. The numbers 1ā6 on the top plot in c indicate the successive waves in the applied voltage and label the corresponding loops in the iāv curves. The insets in the iāv 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
