Q:I tried looking up the the model # and a couple of sites that would sell it but cant find any. Also the player is like 2 years old so hard to find anything about it.

9v is what's called the 'nominal' value, or typical value. Input voltage can dip as much as 20% which would drop 9v down to 7.2v, but is still enough to operate. (If you only supplied a nominal 7.2v, and line voltage dipped 20%, you'd be left with only 5.8v trying to operate a 7.2v system. Not enough.) Basically, every electronic device contains a voltage regulator. Anything more than the minimum is shunted away, but if the input drops, then there is still enough to maintain the minimum voltage necessary to run. But you still need a nominal value higher than the minimum to make sure there's always plenty, no matter what happens.

Q:So my old power cord cable is no longer working and i need a replacement but i cant find one. does anybody know where i can find one? PLease include links

Look for it on this web site (link below). If they don't have it, it likely can't be found.

Q:I have a Karcher power washer which was left outside over night. An animal chewed threw the power cable and so is unusable. I was wondering how to re-connect the power cord together, safely. I do not want to cross wires and use electrical tape. I was thinking of using a connector, but unsure of whether to use a two pinned or three pinned connector.

You can install a plug on the cord to replace the one that was chewed off. Choose one with the same number of prongs as the cord has wires (2 or 3). Be sure to attach each wire to the correct terminal! Splicing the cord is also OK, and tape would not be a problem if applied properly, but I prefer to use heat-shrink tubing. When I do a top-grade splice, I first twist the wires tightly together without making a tail, then I solder them.

Q:Hi,I have just bought a jasper xbox and i know this as it says ''12V, 12,1A'' on the back yet my power cable says ''12V, 16,5A''.I thought that the jasper xbox requires a specific power connector which wont fit the other types. Mine seems to fit fine, so have i got something wrong here? Cheers

i don't know if somethings wrong with your xbox or power brick but i can tell u tho, if u use a Xenon power brick (12V,16,5A) on a jasper xbox u will run into a problem later on, for it will overheat and the CPU and GPU will warp and pull there self away from the motherboard, if u have ever heard of the towel trick( wrapping your xbox in a towel so it will overheat and the solder will pool up and re-solder the CPU/GPU back in place) that's where it come from, i would buy a jasper power brick if i were u (12V, 12,1A).

Q:Whether the weight of the power cable per meter is calculated

12 meters below the road should be used to protect the tube, the use of rigid PVC pipe protection of course, but not necessarily have to wear armored cable

Q:How to connect the power cable pre-branch connector

Pre-branch cable detection: a In addition to routine pressure test, it is necessary to increase the insulation resistance test, with a shake table can be completed in each branch after the completion of injection The table measures the insulation in the finished product After the pressure is also used to detect the insulation of the table to prevent the water cooling process in the branch of the water caused by short-circuit, the general AC voltage test can not detect, can only increase a set of table detection process B Core conduction detection, In each branch body should be tested with the trunk of the conduction test to prevent the production process due to improper operation caused by the branch and the trunk circuit

Q:I'm thinking of the power cables that connect houses to the national grid in the UK. Not only do they appear to be the green colour of copper in full sunlight, but this colour isn't evenly spread. In places there is still black. What causes this, as it's presumably not exposed copper or the colour would always be apparent?

This could simply be moss / lichen or fungus growing. the north side of the cable will have more moss on it than the south side. As the sun is over the equator and England is in the Northern Hemisphere so the sun lights the south side of the cable, and the moss grows on the darker side. This is a classic way of telling directions in a forest or paddock. Garret

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.)

This probably isn't the greatest answer, but I usually err on the side of caution and buy super heavy duty cords. I replaced a guitar amplifier cord last year with a ridiculous, braided cable that could probably power a jackhammer. I've had no problems with it.

Q:Why do phone lines stay on when other lines power and cable will go out during a storm?

PHOne lines stay on when the power lines and cable go out during a storm because they are battery powered and the batteries are recharged by emergency generators.

Q:I blew 2 fuses in my amp in my car, i have replaced them both, one was a 30amp and the other a 20. The 30 amp was an inline fuse from the battery to the amp and the 20 amp was a standard 20 amp fuse in the amp. As i said i replaced both fuses and try the amp again and it wouldnt go. There is a LED light on the top just lighting up a logo, when i attatch the power from the battery the light goes off and when i disconnect it the light comes on. When i dissconect the power the red light for diagnose comes on.

This sounds like a wiring problem i reccomend you completly inspect all wiring to your amp if looks fine then use a test light and test all the wiring if all passes then your problem is within the amp itself. test the remote wire with stereo to car on if wired that way.
