- Q: a usb cable has 5 volts and 2.5 watts. so can it still power if it has 5 volts and 1.5 watts
- Uh...YES! The voltage matches and the current will be regulated by the resistance of the device being powered. It will work fine.
- Q: A pair of Copper wire mains, each of 3.87 sq.cm cross section use to transmit the power, a distance of 915m for 10 hours a day, 80 kilo watt at 200 volts are taken from the mains, find power lost in cable per day at resistivity 1.7 micro ohm.cm.Note: Question is talking about A PAIR OF COPPER WIRE
- Power loss per day is meaningless, I assume you mean energy loss per day, or power loss You have to calculate the resistance in the wire. Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m resistivity Cu 17.2e-9 Ω-m 3.87 cm? = 3.87 e-6 m? R = (2*915)(17.2e-9) / (3.87 e-6) = 8.13 ohms 80 kW at 200 volts is a current of 80000/200 = 400 amps You cannot put 400 amps through an 8 ohm resistance, as that requires a voltage of 3200 volts, which we don't have. So the premise of 80 kW is not possible. Perhaps you copied one of the numbers incorrectly. .
- Q: I'm curious, because I was looking through the 'combo deals' for a part for a potential build, and one of them was a SATA cable (item itself was a hard drive). Does Newegg, or for that matter any major computer retailer, sell products that come with all the cables you need to actually use the part? I guess I'm primarily concerned with Hard Drives and Disk Drives in this case... oh, and PSUs I guess. And the mobo, will that have the power cable?
- Newegg Computer Parts
- Q: Hi! I want to buy I new Hard Drive but I've got a problem. I have the IDE conector but I don't have the Power Cable. It is connected to my Video Card. Can I add a new one? Can I use a power cable from a optical drive(CD/DVD)? Thanks!
- All you need to do is pop down to your local computer store and get a power splitter, just make sure you get the right type, IDE and SATA drives have a different kind of power connector, so just make 100% sure before you buy!
- 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?
- As the resistivity of copper and aluminum are different,to have the the same resistance,the sections are different. The losses per cable are Ri^2 = 0.15*500*50^2 ( just for the sake of completness,the power transmission lines have three cables) If you take lenght 1km you have to use0.15 ohm,which is the same as using 500km and R =75 ohm Be careful to use the same units of lenght in resistivity and distance. You are on the right track
- Q: So I have a subwoofer in my trunk and was wondering if I could use the big power cables (coming from my battery) going into the amp (which is a JL Audio JX1000) to power some LED's that I want to install. My plan was to cut out a small section of the rubber sheath (or whatever you call it) from each power cable and put the clamps from a power inverter on them, then plug my LED's into the power inverter. After putting the clamps on I would use electrical tape or something to cover any exposed areas of the cable. Would this work? If it does work, which color clamp (black/red) would i put on which cable? One says quot;groundand is blue and the other says quot;+12VDCand is red. Also I have a toggle switch near the driver seat to cut the power from the amp so the LED's won't be left on after the car is turned off. Let me know if I'm leaving out any further information needed to answer my question.
- You okorder /... Your power inverter, I am not sure what kind of cabling it will require for it to be powered properly as well. Ground is usually connected to Black. And +12v is usually Red.
- Q: What is resistance of the cable (resistivity of copper is1.7x10^-8)Answer is 14 ohms. But please explain how do we get there in full detail.
- Resistance (R) of a wire is given by: R = ρ.L / A where (ρ) is the resistivity of the wire in Ω.m ; (A) is the cross sectional area of the cable in m? ; (L) is the length of the wire in metres. Radius (r) of one strand = (0.51 / 2) = 0.255 mm = 0.000255 m Cross sectional area of one strand = πr? = (π * 0.000255?) = 2.0428 x 10^-7 m? Total cross section of cable = (12 * 2.0428 x 10^-7 m?) = 2.45 x 10^-6 m? R = (1.7 x 10^-8 * 2000 / 2.45 x 10^-6) = 13.87 = 14 Ω to 2 significant figures.
- Q: Hey y'all , so I got this LG X120 Netbook thing and although it works fine when power supply cable is connected, it won't play just by getting supply from its own battery..also i tried starting it up with the power cable on, and after a few moments I unplugged it, and the screen went black-I mean the netbook was turned off by itself..any help with that? thanks
- It sounds like the problem is one of three things. Either the power cable is the wrong voltage/amperage (these should be labeled on both the charger and the bottom of the laptop and/or battery) If the charger specs don't match the battery specs, it can cause this to happen. Maybe there was a mess-up that caused your to receive the wrong charger. The second possibility is that the battery is bad. A third possibility may be the connection from the battery to the laptop. It may not be making a good connection or could have some internal circuit problems. In any case, if the laptop is still under warranty... I would try returning it. Even if the problem can be fixed from the above suggestions, a problem like this early on tends to be bad news of what lies ahead.
- Q: I have solid interconnects and speaker cable, but I was perplexed by the notion that the power cable that comes with your power source and preamp is somehow inadequate. It seems like another thing to try to market and sell to unsuspecting enthusiasts of an expensive hobby.
- For the level of equipment that most people have it will not be a noticeable difference. In fact in the ultra high end equipment side it doesn't make a huge difference anyway. However those who want the absolute best possible sound spare no expense and will look for the absolute in quality, even if that means spending $10,000 on a pair of speaker interconnects for what most consumers would consider a diminished return and not worth it. Use my 10% rule as a good place to start for interconnects and power cables, but always audition what you buy and if you don't see hear a diference or don't think it is worth it, take it back. But please do not critisice those of us that strive for the perfect sound and image.
- Q: Does anyone know if this PSU comes with a power cord/cable? I can't find an answer for this.
- Psus usually come with one, if not the cable is universal and is dirt cheap
