Joking aside, these theories of why 'conductors' conduct, ie valence, electron clouds etc. don't explain to me why:
I've seen electron 'flow' quoted at approx. 1/32" per second in a conductor- how then do 'signals' travel in a wire at near light speed? If conductivity is a function of electrons at the outer (shell) orbit of atoms, why don't all metals have identical conductivities? Why is a larger % of current supposedly carried at the surface of a conductor?
quote "semiconductors have a valence of 4"- So does carbon, a good conductor.
Duh! I await enlightenment!

Electricity always returns to ______.
The correct answer here is 'the source' if you are looking for the word 'ground' or 'earth' that is not correct. This "electricity always goes to ground" myth is one which seems to be widely held. In a grounded system, the earth can provide a convenient path back to the source (either intentionally or by accident), but the current is still returning to source, not to ground. The ground just happens to be a suitable path back to the source. If you don't believe this, take a battery and bulb and connect them up so the bulb lights (no other external connections, so this is an ungrounded system at this point). Now, using an ammeter in series, connect one side of the battery to ground. You will see a zero reading, because only one point on the system is grounded. (If you drove another ground rod and connected it the other side of the battery, then you would register a current on the meter.) [This message has been edited by pauluk (edited 04-20-2005).]

we detected an element we tentatively called Administronium. The heaviest element yet discovered, with 1 neutron, 12 assistant neutrons, 75 deputy neutrons and 111 assistant-deputy neutrons..... ROTFL! ![[Linked Image]](https://www.electrical-contractor.net/ubb/biggrin.gif)

Double Ditto on the LOL for the Element "Administratium"!!! ROTF, LMAO ![[Linked Image]](https://www.electrical-contractor.net/ubb/smile.gif) Alan, may I print that out and use it at the next Staff Meeting? It looks totally serious, until the second paragraph is read - then it kicked in for me! ![[Linked Image]](https://www.electrical-contractor.net/ubb/eek.gif) Scott35

Show away, mes chers amis, anything on the Net is in the public domain! However, if you DO show it to any Admin people, please try and emphasise several times that it is, in fact, a joke, and that you won't actually be using any Company elecricity to accomplish the final line, (unless very severely provoked).
PS. More humour/humor in the same vein may be found in Scott Adams' 'Dilbert' books-the author used to 'work' (in its loosest meaning) for Pacific Bell you know.........

Just because it is a semi-canductor, doesn't mean it's not a conductor.... In a breif search for something enlightening, I found this: (Scroll down the page. I'm sure you'll find something of your brand of humor in it...) http://hypertextbook.com/facts/2004/AfricaBelgrave.shtml
