Q:hello,i have lots of 8 gauge wire resting at my closet. And i'm very interested on doing the big 3 upgrade to my 2000 mitsubishi eclipse gt. May i see any improvement with 8 gauge wire?...i know that at least 4 gauge is recommended...but i dont want to spend money.

Go cheap, get cheap. Improvement, maybe. But heres a secenario: current draw exceeds capacity of 8 gauge wire, insulation melts, positive wire grounds out, lots of smoke, fire.... no wait... FIRE! Oh s**t that's gonna cost me..... (a lot more than 4 gauge wire I'll bet...)

Q:How are wired differ from wireless doorbells,next how are they installed and finally the cost of them?

Wired have a wire that connects the button near the door, the transformer, and the chime. When the button is pushed, the transformer energizes the chime, causing it to ring. You, or an electrician, must fish wires to a location where a transformer can get a constant supply of power, such as an outlet. There also need to be wires fished to the chime and the button. Wireless work with radio waves. Costs vary widely, depending on the setup you go with. Decent wireless units start around $35-40, and go up from there. New chimes for wired systems start around $8 and up. Transformers start at $10, buttons start around $5. Hope this helps.

Q:chicken wire mesh

you live near a river it will make one fine fish trap round or oval 2 feet in dia.and 4 feet long .let me know and I will tell you how to naturaly bait the trap

Q:1) How does the type of wire affect resistance?2) How does the length of wire affect resistance?3) How does the diameter of the wire affect resistance?4) How does temperature affect resistance?

1) How does the type of wire affect resistance? Wires can be made of different materials , and each material has its own resistance properties, some materials have high resistance and others have low resistance. 2) How does the length of wire affect resistance? Think of it this way , when increasing the length of the wire it will be harder for the electrons to pass through, which means higher resistance it will be. 3) How does the diameter of the wire affect resistance? Small diameter wires have high resistance , because when the diameter of the wire is small it will be hard for the electrons to pass through the wire, unlikely if it has big diameter then it has small resistance because now the electrons can move easy because of its big diameter. 4) How does temperature affect resistance? Temperature also effects wires resistance, when the temperature in the wire increases the resistance will also increase, to understand why imagine your self holding a wire and buring some area in it , what will happen is the heat will melt that section and cut the wire so its like an open circuit which means very high resistance (No electrons will pass through the wire). Good Luck.

Q:How can I investigate the resistance of wire and how it changes with the length of the wireCheers

If you don't have a multimeter, you can probably see the effect of resistance with a flashlight bulb and a small battery (AA or AAA, etc). Get a spool of wire, needs to be coated/insulated wire. Connect the bulb to the battery with the shortest wire possible. See how bright the bulb is. Then, connect again using the entire spool of wire (hopefully you can get at both ends of the wire while it is still on the spool). The bulb will be dimmer because the voltage at the bulb will be reduced by the resistance of the wire (resistivity per unit length X the length of wire). If the length of wire on the spool is too long, the bulb will not light up at all.

Buy in store. Help if know what talking about.

Q:I just bought an exhaust tip with leds which needs to be wired up to the brake lights on my mazda 626. Can somebody tell me which colour wire it is (positive) on the wiring to the brake light? There are a few wires and I dont know which one it is! Thanx

How do you wire this up? You dont !! Beautifying your car is good to do but I have seen these LED tips and they look terrible. If you want your car to look like a cheap honda civic thats been dressed up, then go ahead and do this. if you still want to do this, use a multimeter across the two cables. run one lead to each wire. If you get a positive voltage when someone else presses the brake then the positive lead you have connected will be the side that is positive. If your voltage is negative, then the wire NOT connected to the positive lead is the positive

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

Electric motors, all electric motors, have some form of stator and some form of rotor. The rotor is the section that rotates... duh. The stator is the part that houses the rotor and does not move. AC electric motors, like your fan motors, take advantage of the fact that the phases of current alternate through the wraped wires around both the stator and the rotor. The wire wrappings make the rotor and stator into electro magnets. By careful placement of the rotor and stator wires, the magnetic fluxes that surround both parts can be made to alternately pull and push on the rotor. And that causes the rotor to turn. While most if not all commercial motors have wire wrapped rotors and stators so they are electro magnets, some lab motors may have permanent magnets embedded in their rotors in lieu of the wrapped wires. These are way cheaper, but they are typically way weaker than comparable motors with electro magnetic rotors. So, yes, the coils are electro magnets. As long as there is current alternating through them, there will be corresponding magnetic fields and appropriate forces to turn the rotors.

Q:I'm replacing the ground wire in a chandelier because it has been cut by the previous owner when it was removed from the ceiling. Overall it is pretty simple and I have everything diagramed. When I went to Radio Shack and bought the replacement wire they gave me 18 gauge solid insulated hookup wire. It looks totally different. The ground wire is a braided copper wire (7 strands). Should I go back and take my copper wire with me and get copper or is what I have just as good? An electrician will do the installation of the chandelier into the ceiling.

Ground wire is common convention at electrical boxes. Ground wire from point to point in any circuit is part of the wiring cable used. On a ceiling light, there is little danger of electrical shock if there is no ground wire from the fixture to the metal box. However, your replacement wire will work just fine.

Q:(a) A copper wire and an iron wire have the same length and same diameter and carry same current I. In which wire is the electric field greater?(b) Can a 1mm in diameter copper wire have the same resistance as a tungsten wire of the same length?[Use p(copper)=1.7x10^-8 ohm meters, p(iron)=1x10^-8 ohm meters, p(tungsten)=5.6x10^-8 ohm meters]

a) for them to carry the same current (with equal lengths and diameters) the iron wire must have a higher voltage between the ends. Iron has higher resistance than copper. Because the iron wire has a higher voltage across an equal distance, it has a greater electric field. b) yes, but the tungsten wire must have a larger diameter than the copper.
