Q:How much does it cost to install telephone wires in your household?Does it cost around $200.00 ?

actualy no it cost around 200 bucks to get the line operating its pretty much just an overpriced activation fee becuase no1 really uses telephone lines they just get like dsl lines which is high speed internet/land phoneline

Q:A wire has resistance 56.8 ohms. If another wire consists of the same material but has twice the length and half the diameter of the first, what is the resistance of the 2nd wire?

The resistance of a wire is given by R = rho*L/A, L is length, A is cross-sectional area, and rho is resistivity, which is dependent on material. It will be constant here as we are dealing with the same material. Let's say that the radius of the first wire is r1. R1 = rho*L1/A1 = rho*L1/(pi*r1^2) rho = R1*A1/L1 = R1*pi*r1^2/L1 For the second wire, R2 = rho*L2/A2 = L2/(pi*r2^2) * R1*Pi*r1^2/L1 L2 is twice L1, L2=2*L1. The diameter is half the first, which means that the radius of half the first, so r2 = r1/2. R2 = 2*L1/(pi*(r1/2)^2) * R1*pi*r1^2/L1 = 8*R1 = 454 ohms.

Q:I spliced the stereo wires to the adapter to plug into my car. there's 2 extra orange wires in the adapter. There orange it says there for illumination and the dimmer. What should I do with them? Did I get the wrong one?

Those two wires are useless. Usually I have 3 wires left over. Illumination, dimmer and a blue antenna wire. Your good to go.

Q:hiI got a car radio quot;Grundig WKC 3680to stick to my car, I don't understand is the difference between : 12 VOLT BATTERY WIRE and 12 VOLT IGNITION WIRE, which one to use? I got only one cable bringing the current from my Renault 4 car!thanx

12 volt battery wire is the wire thats always hot meaning theres power always going to it and the ignition one only sends power through it when you turn your ignition on

Q:Wiring together 200 + different colored LEDs. Voltage per LED ranges from 2.5 - 3.6. What is the best way to go about wiring them together and what type of power source should i use?

how the hell should i know?

Q:I have a Trane Heat pump AC/Heat. There are several wires and Im a little stumped? There is a Tan wire*which the book does not show) and a black wire that is labled X1 on the old one but is not in the new ones book? I have also been told NOT TO hook blue wire up to the B port?? But if not, not sure where to put it?

The tan wire isn't used on digital stats you should tape it up. The black wire which should actually be X2 should be emergency heat. And you are correct do not hook up the blue wire to B, you will blow the low voltage fuse or transformer. If the Hunter stat has a C or 24 volt common terminal you can hook the blue wire up there and you won't go through as many batteries. All the rest of the wires should hook up color for letter. GL.

Q:I just bought an aftermarket cd player for my Grand Cherokee and I would rather not have to cut and strip wires so I want to get an wiring harness adapter. My question is, can I just get any wiring harness adapter or do I need the direct connection adapter that is specifically made for Chrysler to Kenwood?

You just get the jeep wiring adapter and then solder or use crimp caps/butt-connectors to connect the wires to the aftermarket harness that comes with the aftermarket headunit. Also, depending on what year Jeep you have you may need an antenna adapter. AND I believe on the Jeeps (like the chryslers) there is not a usable ground wire in the factory wiring harness which means you will need to ground the aftermarket ground wire to the chassis via an existing bolt or drilling. Or, if the stock radio has one of these metal-mesh things affixed to the back, you can use that thing as well. But when you match up the Jeep harness you buy to the factory harness and you will be able to tell if there is ground wire in factory harness.

Q:I'm replacing the door speakers in a 2001 Coupe Camaro with the factory sound system. I needed to know which wire was positive and which was negative so I bought a circuit tester. However, I keep getting the reading that both wires are positive. What could be causing this? I know the circuit tester works because I tested it on the battery terminals and it worked fine.

If you power it up, and go from one wire to ground at a time it will work, if you use the tester between the two speakers wires it will be positive both ways you hook it.

Q:So I customized my guitar, and now I need to wire it. i have a pre-wired pickguard but I don't know how to actually hook it up. There's 3 wires. I have 2 humbuckers, 1 singlecoil, 1 tone, and 1 volume. All I know is that one wire gets soldered to the back where the springs are and another wire goes to the input jack. But there's a 3rd wire and I don't know where it goes. I don't even know which wire goes to what. Please don't post a diagram because it doesn't help. I think the wire colors are white, blue, and yellow. Please help!

OK...I okorder /... That should hook you up.

Q:HiI want to cover a large section of a wall at home with wire. There is a plug socket (electrical outlet) in the wall. How can I ensure that I do not drill into electrical wiring within the wall? Is there some way to scan a wall to locate the wires?Thanks.

The best way to trace where the wires in your wall are would be to use a toner. It consists of 2 pieces... a tone generator, and a small hand held amplifier. YOU NEED TO TURN THE CIRCUIT OFF BEFORE DOING THIS. That being said, you would shut off the breaker or remove fuse for that circuit, open the wall outlet box, pull out receptacle and attach leads from tone generator (they have alligator clips on them) to the white and black. Then you simply turn on the hand held amplifier and place it on the wall starting from the outlet and just keep going in the direction that provides the loudest sound.
