Engineering - February 2007

1. What is having too many amps in a circuit called? (starts with an O)
2. What is something that allows electricity to flow easier?
3. What is a drop in voltage due to great distance electricity travels along a wire (2 words)
4. Has the same current throughout?
5. Has same voltage in each branch?
6. How would you place a negative charge on an electroscope?
7. What happens at the zinc and copper terminals of a wet cell?
If you could answer any of these, that would be FANTASTIC!
Thanks!

all i keep hearing is solar, wind, hydrogen, and the bogus ethanol scam. We have the "Clear Water" filtration thing going on, why not separate the sodium and chlorine and apply the explosive sodium to pushing pistons. duhhhhh!!This is why the aliens coined the phrase "salt of the earth" because of its many uses!!

one plug was being used by a power strip that had 3 items being plugged into it. A lamp, a television, and a heater. I don't think that an overload was the culprit, but I can't figure out what did cause it. Any ideas?

I have a binary distillation system with 2 feeds (different compositions).
Firstly I did the step-off stages with the McCabe-Thiele method and found out that the number of theoretical stage required is 16.
After that I find the overall efficiency with O'Connell's correlation, which is ~50%, thus the actual stage required is 32.
Then how do I determine the feed locations of those 2 feeds?

Do they both work the same way? Is there something like a hall effect sensor that detects the magnetic field in the wire when voltage is traveling through it? Thanks

IF.. you would add enough Tev. (energy) to equal strength electromagnets (3 or more ) and/or accelerators that are orbiting the center , would that cause enough "energy" field to to produce some sort of ( warp, pulse, or diesel ( haha) ) drive. Sort of like the movie FINAL CONTACT -with Jodie Foster with "those electromagnetic spheres".... BUT I AM SERIOUS ....Is something like that possible in theory, because I have been looking for an answer to this question . Unfortunately the Physics that we know today are not able to provide me with the answers am looking for?
