Consider the circuit shown. (Intro 1 figure) all wires are taken into consideration ideal; that is, they have zero resistance. We will assume for currently that every other elements of the circuit room ideal, too: The value of resistance is a constant, the interior resistances that the battery and also the ammeter room zero, and the internal resistance the the voltmeter is infinitely large.
