Q:For my science project, need about 3 feet of copper wire...approx how much will that cost me? I want the wires to be pretty thin :)

Copper wire is probably the most expensive, but you only need 3 feet of it. Best to buy it by the foot and not by the reel. Home Depot has it. Or you can find it online (OKorder for example) as scrap wire but then you've got wait time, shipping, etc. If you know the gauge (thickness) you need, Home Depot will tell you on the phone how much it would be for 3 ft.

Q:im confused which wires are what, theres two wires...no colors?

There is a difference between the wires. One of the wires should have a ridge along its entire length. This is the neutral (white) wire. The neutral connects to the shells of the sockets and the hot wires to the center. once you peel the two wire apart you will see that one has little ridges that should be the neutral. the other way is to use a ohm or continuity meter.The center part of a light socket is the hot. neutral goes to white the other to black. good luck and i hope that this is a help to you

Q:I want two lights on two 3-way switches.1. Power from basement box into light #1 with 12-2 wire. 2. Another 12-2 wire from light #1 to light #2.3. A 12-3 wire from light #1 to switch #1.4. Another 12-3 wire from light #2 to switch #2. Will this do it?

nevermind what I think....the guy under me knows EXACTLY what he is talking about! Do it exactly like he says. His way is better than mine was, honestly, because he has more experience. Thats why I deleted my own answer----we call that professional courtesy to seniority and its what electricians do when someone has more experience than we have speaks up. Now it doesnt matter what I think....I only have 22 years experience and someone with more experience than I has given better, sounder advice than I did. You should listen to him, not me.......or anybody else whom cannot match or exceed his experience. Or didnt you know that all Electricians are part of the same Brotherhood? This is why we always agree (or agree to be wrong). I was wrong, obviously, and my advice, second rate, compared to the advice you are about to get. So.....Pay attention! Wisdom follows!!!!

Q:I recently bought a set of DT Moto emergency lights for my pickup and after installing them i found when i went to wire them to my battery the wire was too short. I didn't install the grille lights just the visor. Could i cut wires from the grille set and wire them to extend the visor light wire?

I'm looking online to find out what DT Moto lights are. Ok, I see what they are. I didn't know the brand name. LED lights in general are not high current, so they probably use lamp cord. I want to explain something to you about polarity. Electronic circuits are sensitive to the polarity of the DC electricity. The positive (+) and the negative (-) connections must be observed. So many people have absolutely no clue about this. There are just two wires. But if you extend them, you have a 50-50 chance of wiring correctly or incorrectly. There is only one allowable way. If wrong, it WON'T work, and probably will blow up the circuitry. So connection to battery or cigarette lighter plug is extremely important not to reverse the polarity. If just the LED lights got reversed, they wouldn't light, but they wouldn't be injured. Just reverse the wiring. But to the 12 volt source, polarity can't be wrong. Not for an instant. If you look closely at the insulation, you will see that one wire has smooth insulation, and one wire either has milti-ribbed insulation, or a single rib down the side. If you extend wiring, make sure to connect smooth to smooth and ribbed to ribbed. Wires should be soldered with electronic solder and the joints covered with heat shrink tubing. No crimped barrel connectors, or twisted bare wires with tape, or house wiring wire nuts. These methods all beg for failure. I don't know about robbing wire from one place and connecting to another. Is the one wire actually too long? You'll never need it? I guess you could take it. But me personally, I'd go get some wire from a lamp store. Match the wire conductor gauge (size), not the insulation size. Most lamp cord is 18 gauge. Some is 16 gauge. You can get 14 gauge or even 12 gauge. Thicker is a smaller number. Places that install car audio systems often have/sell thicker lamp cord. Have I told you enough?

Q:What Spark Plugs and Wires would optimize my MPG? 2000 Bonneville SSEI

AC Delco plugs wires. Using substandard low end aftermarket cheap junk doesnt help your vehicle at all also replacing spark plugs wires really doesnt improve your MPG unless its misfiring badly

Q:If someone were holding onto a high-voltage wire by both hands, why would his/her body have the same potential as the wire? How come his/her body would attain the same potential as the wire?

Any open ended conductor (a human body in this case) making contact with another conductor will automatically attain the same Voltage potential as the other conductor with respect to the opposite terminal of the source Voltage that supplied the Voltage. For example if you make good contact with your finger to the positive terminal of a 12V battery then that puts your whole body at 12 Volts above the negative terminal of that battery. Two conductors in contact with each other will always be at the same Voltage potential at the point of contact. The fact that both hands are on the wire makes no difference because the resistance of the high Voltage wire between the hands is so small compared to the resistance through a human body from one hand through the chest and out the other hand that all the current if any would go through the wire and not through the human body. If however the wire was cut in two at any point between the two hands then one hand would have the full positive source voltage and the other hand would be at reference 0 Volts. Consequently the body would most likely immediately burn to a crisp due to the current through the body. If the body did not disintegrate and current continued to flow through it then a Voltage gradient would be established from one hand to the other with one hand at full wire Voltage and the other hand at 0 Volts.

Q:I bought these speakers and I was wondering what kind of wiring do I need to get to wire them to the amp?

Q:Are those coils of wires in an electric fan magnetic?

coils of wires always are magnetic (if there flows current trough them). the only use of such a coils besides as a magnet would be to deminish fluctuations, like in the fat piece of long usb cables. Else, its always magnetic

Q:i have a 00 gmc yukon and tried installing my cd deck. i pulled off the original harness from the stock deck radio and now its just all wires (its my first so i didnt know), i connect the alpine deck wires and tried to connect them all together. i had a few figure out, except a small noise coming from my stock tweeters every time i step on the pedal. then my speed odometer sensor was going with the bass of my subs... whats wrong? can someone find me a chart of what color wires supposed to go where? thanks for your help

do now no longer combine the speaker outputs out of your head unit. you could harm the final unit this type. you at the instant are no longer harming something via using working a a hundred-watt speaker on a lots cut back powered amplifier (and you will now no longer inevitably boost the sound intense high quality via using switching to a speaker with a cut back skill score). The a hundred-watt score is only the optimal skill it truly is stated for this speaker; it does now no longer propose that it demands that lots skill. in case you pick for extra advantageous skill than your CD deck substances, you will might prefer to function an outdoors amplifier.

Q:Hi,I'm trying to install a ceiling light with a 3 wire configuration (white, black, ground) into a wire configuration of 4 wires (white, red, black, ground). This is configured for two on/off switches.So far, I have white to white, black to black, and ground to ground with the red capped off. This works with one switch perfectly, however when I hit the other switch, the circuit breaker blows.Please help, and thank you!
