Q:Ever time I try screwing in my power cable sparks fly.My amp has no off switch.and my car is turned off.wtf?Help me out/

first off, when installing anything electrical on your vehicle, ALWAYS DISCONNECT THE BATTERY FIRST! (either side will work) on your amp you should see a + POS and - NEG and remote. the remote is 12 volt + POS this is your on and off switch. the lead wire that comes from your reciever (usually a blue wire that says remote, or a pink wire that says antennae) then hook up you pos and neg wires. (IT'S IMPORTANT TO INSTALL A SEPERATE IN LINE FUSE BOX TO THE POSITIVE WIRE THAT GOES TO THE AMP. W A 60 AMP OR GREATER FUSE)

Q:I have a power adapter that changes the tip of a power cable from the US standard to the Spain standard. My laptop has 3 prongs and the adapter accepts 2. It fits into it, but the 3rd prong just rests outside. I know the voltage over there is twice as strong, so will this work correctly?

i hope to goodness this is not just a gimmick that changes from round plugs to flat plugs...make sure it down-steps the voltage too!!! but otherwise, yeah. the third prong is not essential in any country, it's just a safety feature - many homes in the US even don't have it. my one friend installed fake electrical sockets that have the hole for the third prong (but the hole is not connected to anything) and her laptops work fine.

Q:i have a ASUS M4A87TD-USB3 mobo and a Corsair 550 Watts Power Supply. Ive looked in the manual andit says you need to connect the one that ive connected and a 4 pin. It says that if you dont connect the 4 pin the computer wont boot! is there a way around this or it f**ked?

Before purchasing a power supply you should always first check to see if it is compatible with your motherboard in the following two aspects: 1) Does it provide enough power for the motherboard 2) Does it have the appropriate connectors for my motherboard. There are also issues with certain high performance processors requiring very clean or high regulated power supplies (i.e. very little ripple, etc). As long as the power supply offers the voltages you need on one of the connecters, there is probably some sort of adaptor you can purchase... or you could hack something together. But, again, the power supply may have intentionally left off the connector you need because it does not fulfill the strict electrical specifications required by your motherboard. In other words, if you don't know what you are doing, it is probably best to just purchase the correct power supply for your hardware. Forcefully adapting an inappropriate power supply into your machine may later result in unstable system performance.

Q:Also why is it called quot;phantompower? Don't you think there should be a seperate category for technical questions about music!!?

yes a regular xlr will work. phantom power just means the mic needs to be powered 48V. yea, there should be a separate category for tech music questions.

Q:I have lost the power cable which came with my computer's PSU and after looking online for a while the online shops seem to sell the power cables with little information about whether or not they will function with different PSUs so I am guessing it doesn't matter which one I buy.

as long as it fits it should work fine

Q:I have an IVI Checkmate receipt printer, but do not have a power cable for it. Where can I get a power cable for this receipt printer?

Hi.. I think for all your power cable and cable accessories requirement this site can be helpful

Q:HiI'm organizing my cords at the moment, but I'm curious, is it safe to use power cords (say a phone charger) when it is still wound up in a coil? It would save a lot of cord clutter, but are there any drawbacks, as in it would start a fire? Thanks

there is no danger coiling cords.dont fold the cord or you could break the wire

Q:A power cable of copper is stretched straight between two fixed towers. If the temperature decreases, the cable tends to contract; the amount of contraction for a free copper cable is 0.0017% per degree celsius. Show that the stretched cable will snap if its temperature decreases by 128°C.Ignore the weight of the cable and assume Hooke's law is obeyed until the cable breaks. Young's modulus for copper is 11.0 x 10^10 N/m^2 and the ultimate tensile strength of copper is 2.4 x 10^8 N/m^2.

Change in length=(coefficient of expansion)(original length)(change T)= (.0017)(chose your favoret length, I chose 100)( -128 because T is decreeing)=-21.76 Strain = (change in length)/(original length)= 21.76/100= .2176Pa (for simplicity's sake I dropped the negative, rember the wire is in tension) Stress = (youngs modulus)(strain)= (11?10^10)(.2176)= 2.3936?10^10 Pa The UTS (2.4?10^8)<(2.39?10^10) so there is definitely necking and because of the difference most likely there was failure long ago.

Q:I installed a new Power supply after my old one stopped working. I bought a Thermaltake TR2 500W. I connected everything that needed to be connected but it would not turn on. Then i disconnected the 4pin cable that goes to the motherboard, and it turned on. But my monitor didn't detect anything so it just went into quot;sleep modequot;. So every time i connect the 4 pin PCI-E connection to the motherboard it just doesn't turn on. Please help

You might have a DOA power supply or motherboard. It might just have problems with the connections. Sounds like the problem is the motherboard if 2 power supplies dont work on it. I would consider getting a new motherboard.

Q:I purchased a LCD TV the other day and ran a cable line to it (via crawl space). I had to use a splitter to connect the new TV. I connected the cable directly to the TV and then the power cable to the outlet which “popped” and the power went out (breaker trips). I connect the TV power cable to a surge protector and the power goes out again (surge protector wasn’t even on). So I disconnect the cable from the tv and connect the power. Everything is fine until I try and connect the cable...let’s just say the spark was bright and hot enough to melt part of the connector on the TV! So I return the TV and get a different brand and the same thing happens when I plug it into a surge protector. To begin narrowing out possible problems I connect the cable to a regular 10 year old TV with no problems. It is a brand new cable with no cuts or fraying. Any suggestions?

Something is seriously wrong, and you may need to get an electrician on the problem. You need to check the voltage between your set and the cable with a meter. There should be little or no measurable voltage. If you are getting a reading like 115 volts, then I suspect that the wall outlet into which your TV is plugged has been wired backwards, i.e. the black wire is on the white terminal, and vice-versa. The cable is (or should be) grounded where it comes into the house, but if the outlet has the hot wire on the wrong side, this might cause the problem you described. The wrong connection could have occurred anywhere along the line between your main panel and the outlet, so this may involve checking the connections at several outlets and light fixtures - whatever is on the same circuit as your TV's outlet.
