Accuracy
I'm trying to understand this graphic as a whole. My first point of understanding is the resistor. To say that dv=Rdi -- the change in voltage equals the Resistance times the change in current, I don't believe is true. In order to have a voltage drop across a resistor you need a current flowing through it. While it is possible to have an AC current (or a change in current), it is not necessary to produce a change in voltage. By applying a steady (DC) current of 1 Amp through a 1 Ohm resistor, you create a voltage drop of 1 Volt. In that example there is a change in voltage across the resistor, there is a set resistance, but the current remains the same.

Can someone please clear this up if I'm missing something? Jarod (talk) 15:28, 13 January 2014 (UTC)


 * I'm similarly confused. It looks like all the d's need to be removed in the functional relationships. -- Taral (talk) 21:42, 23 August 2015 (UTC)

Typo in inductor equation?
I notice that while the terms refer from first to second in a clockwise manner (e.g. dv=Rdi and dq=Cdv, with voltage being a factor of capacitance but not resistance, and so on), but this doesn't follow when one goes from memristor to inductor (i.e. dΦ=Mdq and dΦ=Ldi). Is this correct? If the relationship follows, I would have expected the inductor equation to be di=LdΦ (i.e. the reciprocal of the current equation). Or am I missing something? — Sasuke Sarutobi (talk) 00:19, 15 March 2014 (UTC)
 * Inductor should be di=dΦ/L if we're following the clockwise "rule".Jarod (talk) 17:34, 16 March 2014 (UTC)

Correct Resistor Symbol Needed
It's a small thing but shouldn't the zig/zag line symbol for a resistor should be used instead of a rectangle. Septagram (talk) 06:59, 14 June 2014 (UTC)
 * I came here to suggest exactly that, but after some quick searching it appears that the US use the zig-zag, and the IEC use a rectangle (see Resistor page). Either would be suitable. Dohzer (talk) 15:19, 15 June 2014 (UTC)
