Electrical Circuit Tests: Life-saving Technology?
In 1998, one of the worst aviation accidents in history took place when Swissair Flight 111 crashed off the coast of Nova Scotia. The flight took off on time from the John F. Kennedy International Airport in New York City and was enroute to Geneva, Switzerland. Two hours and thirteen minutes after take off, the aircraft struck the ocean 8 kilometers from the coast, just southwest of the Halifax International Airport where it was supposed to make an emergency landing. All 229 people onboard were killed.
The investigations following the accident took 4 years to complete and cost nearly $39 million dollars. The Transportation Safety Board of Canada (TSB) determined eleven different factors that contributed to the crash, the first and foremost being the installation of flammable material that could "be ignited and sustain or propagate fire." The fire started and spread so rapidly, the crew was unable to control it and subsequently lost control of the aircraft.
It was also speculated that faulty wiring was another contributing factor. Every commercial aircraft in use has literally miles of wiring; worn insulation of these wires can cause a short circuit, which consequently can cause a major disaster. New, advanced technology has made it possible to prevent tragedies like the Swissair Flight 111.
LiveWire Test Labs, Inc. has developed a cutting-edge device that monitors and detects changes in electrical circuits within high noise environments (such as aircraft). Not only does an electrical circuit test save money on troubleshooting and maintenance costs, it can increase the reliability of the system and maintain a safe environment, certainly of utmost importance for the thousands of airline customers who travel daily.

Fundamentals of Engineering Examination Elegibility?
I'm currently pursuing a degree relating to Electronics Engineering Technology and wish to someday take the FE exam followed by the PE exam. I'm currently Active Duty AF PMEL (calibration technician) and wish to continue with this career field. What I don't know is if the degree plan I wish to pursue will be enough to let me take the FE exam. The link to the degree plan is Thomas Edison State College: Electronics Engineering Technology. If the link doesn't work, I've copied the degree requirements below. Any help would be great. This degree is not ABET accredited and I am a Georgia resident (could also switch to NJ as I'm currently stationed in NJ).
Thanks,
Jason

Electric Circuits Question?
A 87.8-ohm resistor is connected in parallel with a 155.3-ohm resistor. This parallel group is connected in series with a 22.5-ohm resistor. The total combination is connected across a 14.3-V battery. Find (a) the current and (b) the power dissipated in the 155.3-ohm resistor.
I ended up with 0.1820 amps for part A, and 2.6 watts for part B. This is wrong. Please show working if you can!

some information about a computer slowing down?
ok so my computer is doing fine...i've only shut it down a few times since five years but it's still doing great...1 Gb RAM and 100 Gb hard disk only...anyways you don't need to know the rest of the specs...
i am very happy with it, and i recently downloaded a virtual operating system(linux) and started using it on windows....my computer is still doing great...it only slows down when i launch the virtual machine....and i have no problem with that because this is normal and when i close it everything goes back to normal and the computer is fast again....
i told my friend at the university about this and he was like:"this will slow down your computer!", and i said:"no it won't i tried it", so he said something like "the IC's will be exhausted over time" or something like that...but i thought that he was wrong because an electric circuit can't be exhausted!!
so i want from you guys to tell me who was right....(i repeat...i keep my laptop powered on for two months sometimes...it should've been exhausted by now!!)
and if you have time...please give me some information on how a virtual OS works...
