A question about voltage between two points in a circuit

[QUOTE="litup, post: 5641777, member: 129266"] For the purposes of the question the voltages are all the same but if you had a sensitive enough voltmeter, a 4 point probe to be exact, you would see slight differences in the voltages all up and down the wires but the changes would be in the microvolt or maybe millivolt difference because although for the purposes of the question the wire is considered zero ohms, nothing short of a superconductor has in fact zero ohms. It might be 10 milliohms or some such but because the resistance is NOT exactly zero there will be voltage differences along the wires. But not enough to change the answer to the question., [/QUOTE]
