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:how do i connect ignition wire from fuse box to cd player?

find the positive fuse by using a test light on the fuses, when the ignition is on the light your using will light up when the ignitions off it should not light up on the test light, once thats done connect a wire from the back of that fuse behind the fuse box to the terminal run the wire to the stereo wire you need to connect to, twist the wires together use decent electrical tape aroung the join to make sure the bare join does not touch anything else on the car. hope this helps.

Q:wiring diagrams

In the uk the best place to fit a power pump is in the cupboard with the emersion heater. Simply fit another spur fed from the existing one the conections are the same as a 3pin plug brown =live blue=neutral and green/yellow=earth the pump has an internal switch that only operates when you turn on the shower

Q:Okay I have a question I have an 8 gauge wire kit and it says 350 watts peak. What the difference when there is the same 8 gauge wire that says 800 watts peak does this really matter? Thanks guys

properly, there are transformations in conductivity in wires of a similar gauge, based upon the fabric of which the twine is made and no count if or no longer it quite is multi-strand or good middle. That sounds like an quite huge hollow even even with the shown fact that. To account for that lots variance i could almost ought to think of the decrease one is aluminum or some very decrease priced copper alloy. 8 gauge is distinctly thick twine, after all.

Q:Im currently running 8 gauge power wire from my battery to my amp which is a hifonics zxi8408 i have it bridged to 2 channels so its pushing 440 watts x2 to 2 alpine type Rs. The current speaker wire im running is 16 gauge.My question is...since im going to go down to 4 gauge power wire, should I lower the speaker wire and get 12 gauge speaker wire also? What will sound the best?

The okorder and buy some 10 or 8 gauge for the speaker wire and get some 4 gauge wire from them also. The prices are very good. Its really good wire too trust me i have all Knu Konceptz wiring and RCAs in my car with 7k watts. I got about 100ft of the KLMX 0 gauge wire and i'm using the 4 gauge KLMX wire for my speaker wire. You should get some of their 4 gauge it's good stuff with a lot of copper strands... no bullshit...

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.

Q:I'm doin this thing where I need to connect some wires and one part uses Apple iPod headphones. Inside those wires, they have insulation. I burnt the wires so the insulation would not be in the way. Will the wires still conduct the electricity? Or will I just need to find some other headphones without insulation to do this with?

The undertaking of the conductors interior the cable won't regulate, however the insulation would burn and allow the conductors to the touch, making a short circuit. this could circumvent the I Pod working and would harm the output amplifier.

Q:On what actually does ampere depends, thickness of wire or number of turns of wire or what else? Electrical

Your okorder /... and get ohms/1000 ft for the size of wire you select. Also check fusing current while you are there. Eg, #30 has 105 ohms/1000'. So if you have 10' of wire, it's resistance would be 105/100 = 1.05 ohms. Once you have the resistance, use ohms law and the voltage applied to calculate current. For 12 volts, I = 12/1.05 or 11 amps. Fusing current is 10 amps (which is in the open, not in a coil) so you need more length or thicker wire. For AC, and coils, you need more complicated calculations.
