eeneR 3 #3 November 16, 2007 I have to laugh, they kept calling it ConEd instead of ComEd (it is Commonwealth Edison) But ConEd is more the truth I just looked and it is ConEd in NY. I stand corrected, but still laughing at it. Learned something new today!

flyhi 24 #4 November 16, 2007 QuoteConEd instead of ComEd (it is Commonwealth Edison) Isn't it ComEd in Illinois and ConEd in NYC?Shit happens. And it usually happens because of physics. Quote Share this post Link to post Share on other sites

Still find it funny though Just verified it is correct, ConEd in NY and ComEd in Illinois. I still find it funny as all hell though.She is not a "Dumb Blonde" - She is a "Light-Haired Detour Off The Information Superhighway." eeneR TF#72, FB#4130, Incauto Quote Share this post Link to post Share on other sites
Dumpster 0 #6 November 16, 2007 ConEd = Consolidated Edison. Love reading the DC vs AC arguments. As far as I know, AC is the mode of transmission even on the high-voltage lines atop those big steel towers that look like they'd be fun to BASE off of. Yummy.

You'd better be glad it's AC because DC will kill you in a wink of an eye, Gone fishing Quote Share this post Link to post Share on other sites

Most high tension transmission lines are AC, but for various reasons, some are DC. I assume they use semiconductor inverters to convert the DC back to AC, but I'm not sure. Here's an example of a DC line: http://en.wikipedia.org/wiki/Pacific_DC_Intertie "Once we got to the point where twenty/something's needed a place on the corner that changed the oil in their cars we were doomed . . ." -NickDG Quote Share this post Link to post Share on other sites

Dumpster 0 #10 November 16, 2007 Been bit by AC and DC both - Ain't the volts, it's the amps. Guys have been killed changing the ballast in a light fixture. Easy Does It Quote Share this post Link to post Share on other sites

Can't get amps without volts, given a fixed resistance (your body). The current is what kills, but voltage is needed to induce current flow. DC tends to cause muscle reflexes that might make it hard to let go of a conductor, but DC is not as likely to disrupt heart rythms. AC doesn't cause the muscle effect as much, but is more likely to cause your heart to fibrillate or (i guess) stop.

Dumpster 0 #12 November 16, 2007 Yes it takes both!! The DC bite I got was from the elbow to my wrist, while working on a DC drive connected to a 150 HP motor. Very weird. The muscles in my forearm cramped up and that's what broke the circuit. DC doesn't like to let go I guess. Easy Does It Quote Share this post Link to post Share on other sites
bhammond 0 #13 November 16, 2007 I am going through a Hydro Electric course for my job and at the beginning they got into depth about Edison and Tesla, the history books I read as a kid made Edison sound like a genius and hero, it turns out edison was a jack ass. he would go around electrocuting large animals ( once an elephant) with AC to prove how dangerous AC was. the company that Edison formed was the Edison general electric company, Edison soon became such a pain in the ass that the board "offered to buy him out" which then the company dropped the Edison part and became GE "General Electric" Tesla was a brilliant man and wanted to harness energy from the earth and give it away to everyone for free and thats when Mr. westinghouse suggested that they part ways. Edison and Tesla/Westinghouse were such arch rivals, their generators would spin different directions Westinghouse would turn clockwise and General Electric would turn Counter clockwise.
