- 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: Basically, I lost my power adapter to my monitor, and to be honest, I would like to try to avoid buying a new one entirely. I have an old HP laptop power cord that fits into my monitor, but the power specifications on it are different. The power rating on my monitor is 19V and 1.58A. I'm just assuming that's what it needs to run, and that you shouldn't go over that. My power supply from my old laptop converts standard AC into DC at 18.5V, which I'm assuming the difference in voltage between 19 and 18.5 won't really affect anything, but the amperage on my power supply is close to twice as high, at 3.5A output. That's where my concern is, if I where to plug this into my monitor would anything bad potentially come out of it? Don't comment saying quot;Oh, just buy a new one.quot;, I've stated I want to try and avoid that. Thanks in advance.
- It might work,give a try.
- Q: I have a hp laptop from south asia. The adapter connects with the laptop and the power cable. The power cable has a 3 round pin plug which says 6A 240V~. On the hp adapter for the input it says: 100-240V~ 1.6A 5-60Hz. It also says Connect Only to Grounded outlets.Now I am in canada. All i know is that here they have 120 V in normal power plugs. Also they have 1 round and 2 rectangular pins to plug in the outlet.I bought this adapter which basically connects the 3 round pin plug into the adapter and the adapter has 3 canadian pins. The thing is that it says 250V 10A on the adapter. So I am not sure if it will hurt my laptop if I use it. I am a bit confused because Canada has 120V and the adapter accepts 250V. The HP adapter has a range from 100-240V. Will this be ok to use since the HP adapter will just convert the 120V into the proper output for the laptop or do I need one the expensice Voltage converters for the laptop?
- ok here is what i would do .. (get a cheap 5 dollar volt meter at radio shack or such. ) it dont have to be digital or fancy , just need voltage reads.. unplug the lap top from the cord, plug in the adapter with the cord NOT IN THE COMPUTER. take the volt meter , and set it to read dc voltage 250v or above . read the volts comming out of the end of the cord using the meter.. is it less then 250 volts , then you should be good .. if you dont know how to read a volt meter, or know a handy neighbor with one , who knows how to us it , go ask them to read the cord for you , tell them you need to know the voltage output while connected to canadian power from the cord..
- Q: I recently bought a new internal hard drive for my computer (Hitachi Hds721010cla332, a upgraded version of what I currently have). When trying to install it I found out that the power socket isnt the same as my current hard drive. Ive been searching on the internet but cant find an adapter that converts from my current hard drives power cable to the new hard drives required power cable.

- Q: How do I get it not to do that? Its really annoying. Whenever I remove the charger cable , the screen gets really dark. It seems like an actual function and not a defect, but is their a way to toggle it on and off?
- normal, although you can chage some of the settings under control panel as well as using the function key and raise/lower the brightness
- Q: Can anyone explain where I need to plug in the 6-pin cable for my ATI Radeon 1650 Pro graphics card? Or any pictures/diagrams? Thanks!
- to your power supply unit
- Q: I have a ZXi8008 and there's a cable that goes out to the head unit to turn on the amplifier, which is different than the power cable. But in this car, i have not installed a new head unit. Where do I hook up this cable otherwise? It needs a constant power supply to be on.
- i would hook it up to the power cable from ur stero that whay the amp will only come on when the radio comes on. that way u wont drain ur battery, thats if ur talking about the remote cable
- Q: What is the difference between a power cable and an ordinary wire?
- Number tube, you can use the oil marker in the above to write the mark with, there are ready to write a digital, with a few numbers together to form a digital use. A line of both ends to be marked with the same mark, check to see the same mark to know is a line.
- Q: I'm getting some upgrades for my pc and that includes a new power supply with the necessary amperage and 2 6-pin pci-e connectors to power my card. The card is already here but the psu probably won't get here until next week. I want to know if there is any way to run the card from the power coming from the pci-e slot. The card requires 2x 6-pin connectors, but i want to install it now to get that out of the way...
- No, it will simply not work as the additional power supply is needed even for normal operation (not just gaming). This is designed to avoid overloading the motherboard's power circuits.
- Q: So, yesterday I went to a bargain store and I found a Memorex MiniMove Boombox for iPod for 15$ because it didn't come with a DC cable. It has a battery function but it will only charge my iPod if its plugged in. I've been browsing OKorder for a DC IN 6v power cord like it calls for, but I was just wondering if there's anything else I need to be aware of before I consider buying one. Everything else works great, but I really need a charger as well as the stereo because my mom broke my last one and now it work play anything relating to my iPod when its plugged in but that was the only alarm clock I had. Thanks!
- Hard to say for sure. Your best bet is to go to the Memorex site and see if you can download the user manual that will have the full specs for the power cord. Then you can match everything.
