Q: Currently I have a 250GB drive and Writable CD/DVD. I wand to add a 3.51TB internal drive: You should be able to do so, provided you have the mounting space for the drive. You have to watch how you buy the drive - any OEM drive comes bare, with no cables (no SATA data cable). Other box stores selling drive may or may not include the data cable, you have to check. The power cable comes from your power supply, make sure you have a spare SATA power connector from the PSU...

Q: Wire and cable manufacturing process (to be detailed)?: Hello, copper wire per square safe current-carrying 6A, .05X6A = 3A.X220V = 660W, 3AX380V = 1140W, aluminum core for the same 4A algorithm,

Q: Ok so my friend gave me a 40LCD samsung tv, but he had lost the power cable some how. I have actually found a cable to buy on the internet but i have some concerns. 1 i'm not entirely sure its the right cable for my tv, the socket looks like it would fit but the cable claims to work for all samsung song and lg tvs, when i know that my parents song lcd tv has a more complicated power cable. So i'm worried that using this cable could like wreck the tv or something. the second thing is that i herd you can call samsung and they'll send you a cable for free: Go to the Samsung link below. Just put your model into the search and it's parts will come up. Then you can compare the price and type of cable you see there to check what you are buying elsewhere.

Q: i'm using an older mac at uni to do illustration, i pulled the computer round to put a tablet in it and the computer shut down, there are about 20 computers in the lab....the power cable at the back that is connected to the monitor is loose, i tried to put it back in but it's crackling....can i get electrocuted from putting it back in? i can't shut down all the computers so there's still electricity running through...thanks: no prob... no need to b scared jis put the cable in... i do this job all day long.... i knw alot abt hardware... trust me nothing wud happn

Q: I like to play my PSP at home quite a bit. When I do I plug in the AC adapter so that the battery power doesn't get used up unnecessarily. I see that when I have it plugged into the wall that under the system information it says that the power is being used from an external source instead of the PSP's battery. I take it then that the battery won't overcharge and it's OK to use it this way, or do I have to remove the PSP's battery when using the power cable?: It is fine. The PSP is just telling you that it is taking power from the outlet instead of the battery.

Q: Two weeks ago, my 1 yr 19 lcd monitor began to flicker? Why? The power cord and usb cable are secure?: Its possible that the graphics card or the monitor itself are malfunctioning. Try plugging the monitor into another machine to test it. Its also possible the VGA/DVI cable is bad and that is causing the flicker.

Q: On my original PS3 power cable it says 10A 125V, do I have to make sure the cable I use from a computer matches the same?: yes you can due same due its only a cable

Q: im looking at installing an amp and was wondering if its fine to go through the firewall were there is already a group of wires with a rubber seal, i was thinking of poking a hole through the rubber seal and running the power cable through there would this be a suitable option. Thanks: Of course you can. As many amps that I have installed I have only had to drill one hole through the fire wall. As long as there is a grommet you are good to go. You should be able to open the rubber up with a screw driver. Just be careful not to damage any wires.

Q: And twisted pair cable parallel to the laying of the same route with 10kVA 380V power cable, the minimum spacing between the two cables should be how much? Knowledge related to integrated wiring. The The The The: PLC and computer communication cable, different manufacturers of PLC connection is not the same

Q: I have 8x220ah deep cycle car battery's at 12v and i wanted to run an 5kw 12v power inverter but i would need cable which is 400amp 12x4004800 so could i use two cable connected to the battery's and split the power into 2 cable or would this not work if so whythe inverter would be using 400amps from the battery and it would be supplying 20amps at 240voltsis my working out correct: In this case, you should have put the batteries in series to get 48 or 96 volts, that makes the cabling easier. Too late now. Yes, at 5kW, that is 5000/12 420 amps I don't know what size wire you are using, and what the distance is, so I can't help further without that information. For example, if you are running 10 feet of cable (20 total) and you want to lose only 5% of the voltage, which is 0.6 volts, then the resistance of the wire needs to be less than 0.6/420 1.4 mΩ. That is, over 20 feet, 71 mΩ per 1000 feet, which is 000 AWG wire. Mush more than 10 feet, and you need to use MCM wire. .
