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.

How can i use the 19 Dc volt coming from my laptop charger ?
That might be weird ! , but i would like to know how laptop charger works so i can extract the 19 volts out of it to use in an external electric circuit. BTW i tried to just connect a wire to that thin pin at the end of the charger but it didn't work !

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

how to modify my desktop UPS, and add a battery with bigger capacity?
hello everyone , my UPS's battery seems to be dead , it can only last for like few seconds , so i think i have to replace it with a new one, i went to the market and i found out that it will cost me the same as how much a small car battery will cost, so i was thinking that how can i modify the electric circuit in my USP so i can add a car battery to it , as it will last much more longer and it will cost me the same ,i don't care about the way it will look what so ever ,i just need it to work , and i will really have a great benefit of the long capacity of the car battery, so please help
thanks a lot for all of you

The voltage at the load has a magnitude and angle : zero , but the source ?
Hello
i have just solved a problem in (Electric circuits) , and i found a confusing point in the answers
the circuit consists of Voltage source which is unkown , and Tow impedence : Line impedence is = 4 with angle 75
and load impaedence is 20 with angle 30 .
all the impeadences are in series
and the voltage at the load impeadence is 4.4KV ( Line - to line )
the problem says Determine the voltage of the source
everything is ok and i found the Voltage of the source
but the problem is , the voltage of the source has a magnitude and an angle**
while the voltage at the load has a magnitude without an angle or angle =0
it's a bit confusing , i even couldn't imagine that in real life
Thank u so much

Can you help with electric circuits/physics?
4) (part1) Two resistors A and B are connected in series to an ideal 12 V battery. A voltmeter connected across resistor A measures a potential di?erence of 6 V. When the two resistors are connected in parallel across the 12 V battery, the current in B is found to be 2 A.
Find the resistance of B. Answer in units of ?
5) (part 2) Find the resistance of A. Answer in units of ?
6) A resistor with an unknown resistance is connected in parallel to a 13 ? resistor. When both resistors are connected in parallel to an emf source of 20 V, the current through the unknown resistor is measured with an ammeter to be 3 A. What is the resistance of the unknown resistor?
