- 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: If Not What Do I Have To Look Out For Because Im Looking For A New Power Supply Fan.
- The power supply fan is normally built into the power supply. If you are trying to replace the fan in the unit, you will have to deal with taking it apart and probably doing some soldering. Be careful to at least match the specifications of the original fan.
- Q: Hi my new computer's new power supply supports voltage from 100V - 240V. But the power cable's plug that came with it does not fit my country's. My country runs on 240V and the power cable that came with it says 10A 125V on it, and I THINK it's an U.S plug.So should I be getting a new power cable with higher max voltage or just a adapter so that the plug will fit?
- Use adapter is ok. PSU of computer about 400-500W so u only need cable 5A 240v.
- Q: 1) How is the connectivity between 2# of 300AH battery and 200A Power plant made?2) Need to know the cable sizing between battery and power plant.3)calclation to arrive at the sizing of input cables, output cables and charging cables between battery and power plant4) Are charging and discharging paths same in the batttery? ie when load is on battery whether the load current flows through the same cable of charging ?5)A photograph of the system will make me understand the solution better
- The battery and power plant statistics do not enter into the calculations. I assume that the load is continuous, and the battery is to be continuously trickle charged. The power plant will have to deliver the load current and battery trickle charging current, at the voltage necessary to charge the battery. You will need to know the load current, the trickle charge current, the distance between the power supply and the battery (or load if you connect directly to it), and the voltage necessary to supply the load and trickle charge the battery. The voltage drop will be the total current multiplied by the total circuit resistance. this resistance will be the sum of the individual conductor resistances. As an equation, this is Voltage drop = total resistance times current in amperes. The total resistance will be the voltage drop divided by the current. Now you know how much resistance you can stand. The National Electrical Code in the US has tables showing the resistances of various sizes of wire, and how much current they are rated to carry. From these, or maybe from you wire supplier, you can find out what size wire you need. It will need to be large enough to supply the voltage and current, and have a rating for at least that much current.
- Q: Two weeks ago, my 1 yr 19 lcd monitor began to flicker? Why? The power cord and usb cable are secure?
- I've had a similar thing happen with my 17 GEM monitor. Eventually, I relocated the monitor and redid all the wiring and the flickering ultimately stopped. I'd wager it's a wire issue.
- Q: cables? Power strip? thanks
- cable or direct TV you need a new converter box. I have cable and it is $5 a month more. Lady at work has Direct TV adn the box is $100 a year more. It has many more cable connections to the back to the Tv and does improve the quality and picture. Power strip option. You can but I do not..... Good luck.
- Q: I recently bought an asustek computer with a 350 watt PSU. Unfortunately, it did not come with a power supply cable. I have a quot;king-cord10 amp 125v 1250w cable numbered KC-003. Will this cord work to power my computer, is it too powerful, not powerful enough? I don't want to plug it in and over power it or somethig. Thanks for the help.
- Just get a kettle lead. Its the one which has 3 holes to plug into almost everything.
- Q: im running 4 ga power cable through my 2003 civic and im wondering if anyone hase any good places to run it through?
- yes okorder /
- Q: what does the power cable that comes with video cards do? is it for when u dont have a 6-pin power connector or something? j/w cuz im thinkin bout gettin a ati 3850 and it requires a 6-pin connector, but yet i know 2 dudes with the same psu as me, runnin a ati 3850 perfectly.HP Hipro 300W 12V 19amps but yet it doesnt have a 6-pin connector
- That's right, the power cable is in case your power supply doesn't have a 6-pin power connector. A 300W power supply for a 3850 is cutting it a bit close, but you'll probably get away with it if the rest of your machine is typical. (Typical machines with a 3850 are just under 200W peak. See link.)
- 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.
