Q:The difference between a fire resistant cable and a general power cable

First with the liner is the fire-resistant bridge, fire bridge is only the surface brushing fire paint, and some design drawings are written and norms a bit vague, according to his drawings should be refractory bridge.

Q:My power supply cable to the motherboard is only 20 pin and the motherboard has a slot to take a 24 pin power cord. The 20 pin will fit but 4 slots are just left empty. The motherboard LED light comes on showing it has power. When I try to boot up the motherboard runs but the hard drive doesn't boot or the screen isn't working. Could this be b/c of not having a 24 pin power cable?I know the video card and HD work b/c I just transfered them from another motherboard that was a 20 pin. Any ideas?

I believe it'll work, 4 pins will just hang off to the side. The same goes for 8 pin power cables to a 4 pin power socket on the motherboard.

Q:i have a ASUS M4A87TD-USB3 mobo and a Corsair 550 Watts Power Supply. Ive looked in the manual andit says you need to connect the one that ive connected and a 4 pin. It says that if you dont connect the 4 pin the computer wont boot! is there a way around this or it f**ked?

Before purchasing a power supply you should always first check to see if it is compatible with your motherboard in the following two aspects: 1) Does it provide enough power for the motherboard 2) Does it have the appropriate connectors for my motherboard. There are also issues with certain high performance processors requiring very clean or high regulated power supplies (i.e. very little ripple, etc). As long as the power supply offers the voltages you need on one of the connecters, there is probably some sort of adaptor you can purchase... or you could hack something together. But, again, the power supply may have intentionally left off the connector you need because it does not fulfill the strict electrical specifications required by your motherboard. In other words, if you don't know what you are doing, it is probably best to just purchase the correct power supply for your hardware. Forcefully adapting an inappropriate power supply into your machine may later result in unstable system performance.

Q:i have an hp7500 and their is only two pin spots on the 9400 cable

Huh? Do you have the right model #? The only cable on the 9400GT should be the fan cable, and it should plug into the card itself (see picture in the link)

Q:Copper and Aluminum are being considered for the cables in a high-voltage transmission line where each must carry a current of 50A. The resistance of each cable is to be .15ohms per kilometer.A. If the line carries power from Niagra Falls to New York (500Km), mow much power is lost along the way in the cable? Compute for each choice of cable materialB. the necessary cable diameterC. mass per meter of cable Please correct if you see anything that may be offSolving for part a:Power = I deltaV, since deltaV was not given IR=deltaVso Power = (I^2)R = 50^2 x 75 = 187.5 kW lt;-- answerR= 75 since R= .15 ohms/ km x 500kmB) resistivity of copper = 1.7 x 10^-8 ohm m resistivity of al = 2.82 x 10^-8 ohm m R = (resistivity x length)/Areawhat do i use for R? is it the 0.15 ohm/km or 75 ohm?using the 75 ohm as R, I get that the radius of the copper wire is 0.0000361 m and the diameter is then 0.0000722.Am i on the right track?

I think you went wrong with the length. If R= (resistivity x length)/Area, make sure you are using length as 500,000m as the units should be in meters, not km. R is going to be 75 ohms because you are considering the entire length. Then solve for area and radius.

Q:The question above relates with the Transpose Line.One of the subtopics under Transmission Line Parameters in Power System.

If the adjacent line induces current in a nearby cable that would be a problem. Transposing results in one section having an induced current with a certain phase but the next section (after the transposition) has an induced current with the opposite phase. Over the length off the cable, the opposing induced currents will cancel each other out.

Q:My laptop cable sometimes won't stay in all the time. When it is connected, it has a blue circle around it, but sometimes that blue circle goes off (while it is plugged into the side of laptop) and the tool bar changes from showing a plug to showing a battery. Would there be something wrong with the cable line and it needs to be replaced?

the power plug is damaged and will have to be replaced the cost about 90 to 125 dollars. look at it and make sure if it is the plug or the socket

Q:what wattage do you need, how many power cables going into the graphics card and what type etc

The psu in your pc will need to be supplying between 450 and 500 watts.

Q:The cylinder is in the power cable about 2 inches from the connection to the laptop and is about one half inch diameter by one inch long. Does it serve an electronic function or is it just a mechanical assist device?

It's called a choke. It's used to filter out unwanted radio interference.

Q:I bought an SATA hard drive off someone that appears to use a 15-pin connector. There does not appear to be any other connectors on the back. How does this thing get powered? I have another SATA hard drive that uses the regular 7-pin connector, and on the back, just like an IDE drive, it has a place to connect the power. This SATA hard drive though just has that big 15-pin connector in the back, and nothing else.
