running RCAs by power

I am here to entertain! and something else, just can't remember.

Again this was gathered info from a physics professor. Your explanation is sound, however in your previous responses it was stated that AC current does produce a EMF, but the magnitude of this will not affect low level signal, but a metal wrapping in an RCA will amplify this interference. Yes a shield is used to block things so to speak, but after all it is a conductor.

Oh MY GOD..........come on "boys"...where is all of this taking us? And yes I said "BOYS".    You kids babble off this crap that is supposed to impress us, honestly it just makes the rest of us just want to "walk away with our tails between our legs" How many people do you think understand HALF of the crap you kids are spewing......and does it really help ANYONE. It's like the main objective has been forgotten....to help, and assist...the "not so experienced"

I would think this would be a perfect topic for you guys to PM the living crap out of one another over...........

Well Kar TuneMan you sure like to spoil other people's fun! Perhaps this topic is a little beaten, but at least it hasn't been reduced to name calling and other juvenille behavior (yet). Just because you can't join in doesn't mean you have to condemn it. (this should be read with a humorous inflection)

I for one have learned a lot from this thread, and am quite happy to have participated in it. It may take some time to figure this stuff out (there are some things I am not totally clear on) but there are answers to questions here. Be patient, this is after all a DISCUSSION forum...

If nothing else, use this to recognize things you don't know about and read up on them. Try to learn more. Is it surprising that DYohn and Hamfisted (sic) know stuff like this?.. they are two of the most knowledgeable people on the board. Do you think they ever stop trying to learn?

Heh.. here's a post from another place I read..

"My Marks Manual lists the simplified final velocity of a rocket as delta V = I(s)*g*ln(w(i)/W(f)). This means that the specific impulse ( the I(s) term) times the natural log the final weight over the intial weight. Modern rockets often have a final weight of 10% of their initial weight (90% fuel), which gives about 2.2 for that part. I can not find the specific impulse of gun powder, but we can assume it is fairly low, which is why no one uses it and therfor it is not listed in my book. The lowest specific impulse listed is for hyrdazine, at 110 seconds. That give a maximum speed of 7,734 feet/sec. Escape velocity is around 33,000 feet/sec, so there is no way it could have reached orbit. If they fired it at a 45 degree angle, it would take about 170 seconds to reach its highest point, and another 170 seconds to hit the ground again. With a horizontal velocity 5468 feet/sec, that gives a max distance of 352 miles, which makes things at least possible."

Dwarren, just a quick correction.  This professor is telling you the braid would make more noise because in his mind it is like an antenna, paralleled with the center conductor.  The only problem with his view is the "antenna" is grounded at both ends.  Haemphyst's assessment is correct.
