Denominator: dq
What this part means
The complete quantity below the fraction bar; it must be nonzero for this division.
Its job in the formula
dq occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula
In 1971, Leon Chua published “Memristor — The Missing Circuit Element” in IEEE Transactions on Circuit Theory . His argument was one of pure symmetry, not empirical discovery. Circuit theory recognizes four fundamental variables — charge, current, voltage, and magnetic flux linkage — and, in 1971, three of the six possible pairwise relationships among them were already embodied in named components: the resistor relates voltage and current, the capacitor relates charge and voltage, the inductor relates flux linkage and current. Chua noticed that the sixth relationship, between charge and flux linkage, had no corresponding physical device, and reasoned from the completeness of the other five…
Learn the underlying idea
A fraction a/b means a divided by b. The top number is the numerator; the bottom number is the denominator, and it cannot be zero.
