"Logic tells us that current flows, so by the process of elimination, it should be somewhere between zero and 186,000 miles per second."

This basically allows me to state an obviously worthless opinion without fear of being wrong. ( I love quoting myself [Linked Image])

"What I'm getting so far, is that with a pressure (voltage) applied, electrons would wobble, oscillate, gererally move around inside the conductor, without a complete path to generally flow."

Basically, yes. When a froce is applied to a conductor, there doesn't have to be a complete path for current flow.

The prime example of this is the charging of a capacitor. When voltage is applied (let's assume a DC source for this), the electons are forced to one end of the circuit while the "holes" (as Radar pointed out) go to the other.

( At this point it is important to remember that "hole" does not refer to your supervisor).

During the time that it takes the charges to go to their respective end points, there is "current flow". Once the charges at the end of the circuit equal the charge that created it (a battery for instance), the current flow ceases.
