Schematic illustration of the linear and memristive-like behaviors for all the four fundamental circuit elements. The linear relationships of the four basic circuit variables define (a) the resistance, R , (b) the capacitance, C , (c) the inductance, L , and (d) the transtance, T , with only the transtance T being both positive and negative. Accordingly, (e) the memristance, M R , (f) the memcapacitance, M C , (g) meminductance, M L , and (h) the memtranstance, M T , are defined by pinched loops of the basic circuit variables. For M T , the butterfly-shaped loop in panel (h) occurs at a sufficiently large input of q .
