I've got to go take a test on may 5th for a general mechanics position with the post office. I need to get some books or something to refresh my memory on the basic electrical stuff like calculating loss thru resistors, the relationships between amps, watts, volts, etc, and other basic stuff like that. I aced their little mini test on the mechanical stuff, and passed most of the electrical stuff too, but the real test is like 3 hours long. I have forgotten to much of this stuff!

did a quick search and found this site: http://www.autoshop101.com/autoshop16.html

Here you go. DOE Basic electricity Technical Standards volumes 1 thru 4.

Thanks!

Thanks for the DOE Handbook. It instructs electron current flow in the correct direction, Vol 1, Page 40.

When was the last time you knocked on your butt by hole current?

Everybody knows the electrons don't flow :D . If they did the copper wire would eventually just disappear as the electrons worked their way from one end of the wire to the other.

The holes flow. graemlins/beers.gif

The reference is page 10 and 11 of the manual, page 34 and 35 of the pdf file.

I got a pile of these DOE manuals, everything from Nuclear Physics to Fire Protection. This is the stuff the DOE expects you to know in order to get a license to operate a nuclear power plant.

There are both negative and positive flows. Electron holes flowing are positive flow like Lightning originating from the ground and traveling skyward. Negatively charged lightning comes from the clouds and travels downward. Positive lightning is by far more intense than negative. Electrons are not depleted from the copper atoms, there are grounded resistor banks on generators providing a source to ground.

The majority of electrons flow on the outside of the conductor versus through the inner crystalline metallic structure of a copper or aluminum wire. If a conductor is overloaded, which is current fighting the resistance/impedance, then the resultant power loss is manifested in heat or I squared R losses. That's when conductors start sagging between poles. The conductor does not dissolve unless massively overloaded by a ground fault or phase to phase fault, then the rapid heat generated can make metal transform from solid, to molten liquid, to gas vapor in a blink of an eye. Vibration from wind is an important factor as that can cause the conductor to become brittle over a period of 30+ years.

The electrical theories in these PDF documents are not a big emphasis for a potential candidate for operating a nuclear reactor as compared to the theories on heat transfer and fission. Reactor theory is based on the six-factor formula for neutron leakage, fast fission and slow fission, which are the reproduction rate of neutrons and the decay life of fission daughter products.

Previously in another capacity, I was Cold licensed senior reactor operator in 1983, with Westinghouse PWR certification from Zion Illinois. During the written, oral, and simulator exams none of the basic electric stuff was asked by the NRC examining team.

The referenced electrical theory is useful for someone like myself that operates the electric system. And then, understanding square root of three for applications of 3-phase power and volts amp reactive VARs (power factor) are a more day-to-day concern. Utilities measure three phase voltage by phase to phase relationships. However, on a single phase feed from your service panel, voltage is related as phase to ground voltage.

I didn't mean that this basic electricity book was what the DOE and or the NRC requires, but the whole series of book as background information leading to the license. Plant specific info is much more important to the CR operators than the theory of electron flow.

Shocking !!!!

:D :D :D

Yeah,......... What bonecrusher said. :D

Ummm, guys, this is only a BASIC test :eek: If their going to ask questions like that fo a mechanics position, I guess I had better practice my "would you like fries with that" routine.

At any rate, I appreciate the effort put forth by MarkC for the reference material. Thanks, once again!! :D

travis, you might want to practice "Would you like a diet soda with those fries?"

Current flow is really made of vibrating strings in 5 dimensions. :D Really, before you convince yourselves how current really flows, consider that much of what is known by science is models that mimic observed behavior. Until we can cram ourselves inside the molecular structure of a wire and see it with our own eyes who really knows. But it makes for an interesting debate none the less. The important thing is to understand how various models support observed behavior.

Or, "would you like a diet coke with your super sized fries and double meat, double cheese artery clogger?" tongue.gif Hey, I can do that graemlins/thumbsup.gif :D
