Q: I need to select a power cord for a computer and other appliances (like a printer). Power cords usually have their amps and voltage (capacities?) imprinted on the outside. What is the rule of thumb for selecting a power cord and why?For example, if my printer has the following requirements:Power Source AC 120V 50/60 HzPower Consumption - 5W-350WWhat amp/voltage type of power cord will do the job?I am of course concerned about overloading the cord with too much electric requirements.(People who actually know this matter SPECIFICALLY only need to reply; please excuse if the electric language is not used right.)
A 5A cord would do the job.
Q: i herd that 2 cables in a network (ethernet) cable just carry power. and was wondering which 2 colours or on what side the 2 are.also how much voltage they carry.was hoping to make an easy router mod to stop with the head issues.cheers.
you did not state anything that will help anyone tell you that imformation you have to know what kind it is and it still would be very hard to just tell you the voltage and everything like that
Q: Mine isn't so I'm just wondering what it would do.
A thick power wire that carries a lot of current or power has anEMF - electro magnetic field around it. This field can will pass into the RCA cables - the cables that carry sound from headunit to the amp. You want the RCA cables to be as 'clean' as they can be for the best sound signal and quality. This field will interfere with the RCA's, especially low quality cheap RCA's. causing interference and poor sound quality.
Q: Things to think about: -valley has steep sides -the slopes are rain forest or small villages -no roads built in the area -the cable towers are 5000 ft apart at some points, but others only 3000 ft -the towers are 15000 ft above the floor, others only 500 ft*activities must not create significant noise*Cables are not allowed to sag below 120 its for my technical report for civil engineering technology....any ideas will help even the craziest ones..thankss soo much
That's a long span, but not impossible. You might want to check out the Ameralik span in Greenland for some ideas (it is about 3 times that long, at 5376 meters) Here's one reference:
Q: I have a Scientific Atlanta Explorer 8000 DVR Digital Cable box and yesterday when I arrived home, it was not showing the time or any evidence of power. The TV and DVD player work just fine, but not the box. I unplugged it, tried a different plug but no power. I hear the box working, but it never shows any sign of powering on. This box is maybe a month old.Any thoughts?
I have a Scientific 2200 and it won't power on either. I've tried everything. It happened 2x in the last week. The other time it came back on by itself after a little while. This time -nothing. Tech is coming tomorrow. Better be bringing a new box......
Q: I am getting a new 160 amp high output alternator for my 2005 Mazda 3 2.3L. I am running a 1000w amp with two subs. I have the stock alternator in it right now. There are two power cable kits available for me to get. One that has 4 gauge wire with a 100 amp fuse and the other, 1 gauge with 150 amp fuse. Which kit should I get? Can I just add 4 gauge wire along with my stock wire instead of the 1 gauge kit? What are the fuses for and which one would work better? I know nothing about this. Thanks.
A fuse is a necessary circuit protection device, if there becomes a short in the circuit, it can cause a fire, the fuse is a precise conductor which will break if too much current (energy) is being drawn. A 4 gauge wire will work fine, and you need a least a 160 amp fuse, any less and it will blow if your alternator is at full load.
Q: I have had my Sony Laptop for about 2-3years. And only recently is it acting weird.When I have my power plugged in, the laptop runs fine and can be on as long as the power cable is in. But as soon as I take my power cable out, it automatically shuts down.I checked the power management, and it says my battery has 0% power. I have tried taking the battery out and putting it back in, but it still does not work.The lights on my laptop indicate it is charging, but it does not put any power into my battery and the only way it can run is if my power cable is plugged in. The battery is pretty much dead :/Is there any solutions to this? Considering I bought it in the UK and now live in the US
The battery is toast. You will most likely need to buy a new battery for it.
Q: I have a SATA DVD burner SATA 160GB HD .... but the PSU only comes with ONE SATA power connector .... great ..I was thinking about buying a SATA host controller card ... but I found out that that will only give me more SATA ports and take up one of my PCI slots LOLThen I was thinking about returning my SATA DVD burner for an IDE DVD burner ...
confident you go with as many SATA cables as complicated drives. potential for the HDDR's comes from the potential supply. confident you diskpersistent demands potential from the potential supply. i think of for the GFX card you're taking some 6 pin PCIe connector returned potential supply.
Q: I bought a 9800 gtx card, and it needs 2 power cables connected to the power supply for it to work. It's a monster card. My power supply has one pci express power cable only. Will I need adapters to plug into my power supply?
The adapter must have two of the four pin Molex connectors. It uses three of the wires, in the four pin Molex connector. (3 wires x 2=One 6 pin PCI-Express power connector)
Q: What is the meaning of YJVVV and VV22-4 * 25 + 16 in electrical appliances?
Should be caused by power line interference. You can buy a shield with the copper wrapped in audio cable and then placed next to the power cord can be, electronic city should have to sell.
