Why is voltage constant in a wire?

Considering the OP's education level your post may be confusing.

Just checked his profile: Degree in Chemical Engineering (undergraduate?)

Yah, I know what Sheldon said about them; "Hello, Oompa Loompas of science." [ref]
Having only gotten a tad past halfway through my attempt at a BS in EE, I found that comment hilarious; "Wait? What? What does that make me?"

I would attempt to make more funny jokes about this thread, but it's a very interesting topic, as, I've discovered over the last few years, that I don't know what a "Volt" is, and am very interested in seeing a solution.

ps. Spent the whole morning trying to figure this out, only to prove, mathematically, that, at the atomic level, electricity doesn't work.
pps. Unless you drop down to the milliamp ranges, and then, electricity works again. Whew!

Assuming people's qualifications can be a risky business.
Yesterday, I dusted off some of my certificates.
