Q:Ok so I was doing something stupid just now. Cuttiing a power cable that connects to the tv. Halfway through to cutting it, the wire explodes and hit my face o,o. So quickly, I turn all of the switches off and run to wash my face. I just wanted to know whether it's ok to turn all the switched back on cus I'm literally in the dark right now. And will there be any damage to my face since the wire explodes in my face?

Everything will be fine to turn the switches back on, but you must unplug the cord you were cutting first. If not, you'll hear another loud pop as the breaker switches off. Unplug the cord, then turn the switches back on. Before you plug the tv in, check the cord going to it for burn or charring. If you do not see any, then stand to the side of the tv away from the screen and back, and then plug it in. Be careful. Unplug the cut cord first!!!

Q:We need 25cm distance between Cat series cables.Can we wire Coxial Cable in the same conduit with a power wire?if yes than whats the reason for both Coxial and Cat Series Cables

Check with city laws vary but no they don't want coax in the conduit with power wires

Q:my portable HD has 2 USB cables, one for the computer and one for power... why?

Because it needs more power than the standard 5V the USB normally gives.

Q:HiIs it advisable to run 110VAC cable from the sub stationa and 110VAC cable from generator (clean) in the same conduit ; one of them for lighting and the other for CCTV; the concern is if the one for lighting is not clean (not consisting of a pure sine wave or carrying interference) would that effect the power line of the CCTV and has an effect on the picture? even though both are 110VAC.the installation is over seas where the power from the station is not consistence.

If both are simple power lines, then you won't have a problem. The only time you need to be cautious is when you are running a high-voltage power cable and a signal cable alongside each other e.g. a 110VAC cable alongside a 4-20ma signal line from a transmitter. The reason for the potential interference is that the power cable emits an electro-magnetic field which can potentially cause induction in the cable alongside it and effect the signal with an induced EMF. The likelihood of this depends on the cable type, screening and correct earthing measures. It's a good bet to never run a power and signal cable alongside each other, and if you have no other choice, seperate them by means of a makeshift Faraday Cage. If both are doing nothing other than supplying power to the system though, then any induced EMF will be so minute, it will not likely affect the system in any way.

Q:I have this printer, bought for $100 at Best Buy a few years ago... I moved almost 2 years ago, and seemingly have lost one or more of the cords associated with this printer. Im trying to find out which one is missing. I have the one which connects the printer to the computer [USB]. But I dont have the one that gives it power... It looks like the end would fit into a 3 hole [prong?] opening, the holes are all in line... Anyone got an ideas? Know what Im talking about? If so, any idea what its called, or where I can find one? Im sure online, but I havent any idea what Im looking for at this point.

why don't you e-mail HP see if they will send you a power cord or advise you where to get one in your area

Q:can we use welding cable to hook up amp in our car?rated 200amp

There is no need for a 200 amp cable. most of the time 75 to 100 amps is more than enough. Just go to the local car audio store and pick up a amp kit. (Depending on amp size depends on price) The local Wal-Mart sales them as well. You'll spend between $25-$100 for a good amp kit. Amp Kit 1 power wire 1 ground wire 1 set of RCA for audio from sterio to amp 1 fuse.

Q:I am thinking about buying a hard drive and a SATA to eSATA cable to get more space to store things but I dont know whether or not the eSATA cable supplies power to the hard drive like a USB port. Do I have to buy a power cable for the hard drive or will it work without one?

I use an external sata for backup with a usb cable converter the power comes from the usb cable, esata I suspect would be similar unless you are hooking it up with arj45 or something?

Q:Is it safe to connect the case fans in line with the hard drive, or should I use a separate power cable?

If it's a newer motherboard and case, there should be jacks on the motherboard itself for the fans . It should be safe yes. There are minute reasons why you might not want to, but the odds of interference or power supply variance are quite remote.

Q:Why did my power supply entrance burn with the power cord cable the stats of my computer are: HP Compaq dx2250 Microtower PCProgram: Windows 8 32bitPowerSupply: 500w MaxGraphics Card: Nvidia Geforce GTX 550 tiWhy cause it to burn? What should I do? Change the power supply or buy a better power cord cable. The cable that burn, I bought it on OKorder for $2, I am not sure if this cause the problem, but for sure I need to buy a power supply because the entrance burn. What should I do? Is my computer stable with all this stats? What cause this to happen? Was the cheap power cord fault? I don't know, please answerThank You,

A dodgy power cable can very easily singe or burn the power socket on the computer. In general, the lighter the cable, the more dodgy it is. $2 is nothing - I would buy a more expensive cable. The cents you save isn't worth it when your house is on fire. It's impossible to know whether your power supply or other computer components suffered any damage because of the electrical fire. You could try testing with a multimeter, but you should probably replace the power supply at a minimum.

Q:Hi,1) Is spinning down of hard disk same as removing the power cable of the hard disk ? 2) Will the IDE cable connected carry power to the hard disk when the power cable is removed ?3) How do we spin down the hard disk manually ?

1) When you unplug the power cable, it spins down, because there is no power. In order to read data from the hard disk it needs to be spinning. When it is not spinning, you cannot read data from it. Some power saving systems will allow you set the hard drives to spin down after a long time that it has not been used, to conserve power. After that, to read from the disk it needs to be spun up, and that takes a few seconds. 2)No. 3) You cannot manually spin a hard disk, it spins at 7200 (some models 5400) rpm. That's VERY fast.
