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)[reply]
