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.

My tenants tripped the electrical circuit breaker and now they want me to lower rent.?
My tenants recently tripped the circuit breaker in the kitchen and now they want me to lower the rent. The circuit breaker is their for a reason so they don't blow a fuse. Nothing was damage and there was no fire. The reason it tripped was because over 5 electrical appliances plug in at the same time including the refrigerate. They got their power back on. I asked them was microwave running while the foreman grill, crook pot and toaster oven was also running. They said yes. I told them they can't have all that running at the same time or it will blow a fuse. I told them a simple solution is to get a power strip that will prevent the power from going out. Next thing I knew a few days later they want me to fix that or lower the rent by $250 or they will break our 6 month least and find another place to live. Technically the circuit only trip once and also only in the kitchen. It didn't made the house inhabitable or anything. I think they are trying to low ball me because their recent PG&E bill was high. By law they have nothing against me to force me to lower rent or break the lease.

Math question Help Needed?
1. Find x and y so the following equation is true.
3x-2yi=3+10i
2. Find x and y so the following equation is true.
(6x -1) - 2i= 6+yi
3. Complex numbers may be applied to electrical circuits. Electrical engineers use the fact that resistance R to electrical flow of the electrical current I and the voltage V are related by the formula V = RI. (Voltage is measured in volts, resistance in ohms, and current in amperes.) Find the resistance to electrical flow in a circuit that has the following voltage and current
V=(100+60i) volts
I= (-6+2i) amps

Electrical Circuits!? I NEED HELP?
I have this science voltage lab tomorrow, and were doing squishy circuits. We made simple circuits the other day using play-do, a battery pack and some L.E.D lights, but now she sorta wants us to change the circuit.
Simple: I need a dependent and independent variable
I was thinking that i could change the medium and measure voltage but i don't really know how i would go about doing that! ;o
