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.

first, do not remove any of your factory wiring. only add extra wiring. it would work if you did two or three runs of 8 gauge wire instead of a single run of 4 gauge wire.

Q:What are the advantages / disadvantages of different types of wire (ethernet, coax,twisted pair) over the different types of wireless( WI- Fi, bluetooth)

wireless is slower than 10/100 according to readings on p c wireless is mainly for convenence

Q:In the picture there is a blue wire that is loose, also i just had the starter and wiring changed a month a go. Thanks.

The blue wire I see is attached to the Oxygen sensor (O2). If that is loose there must be a plug where it goes. That is not shown in your picture. If you're saying the car won't crank (different from will crank but still not start) what is the wire with the blue cap that disappears behind the exhaust manifold? Here's how starters are wired: The BIG red wire comes directly from the battery to the solenoid. Also going to the solenoid is/are (a) control wire(s). Typically there's only one control wire. When you turn the key you energize the control wire. That in turn pulls the solenoid in sending the starter gear into the ring gear on the flywheel. The solenoid also makes contact between the BIG red wire and the actual starter motor itself supplying power to the motor and starts spinning the engine. Older model cars have the second wire going to the solenoid do so to supply unresisted 12 volts to the ignition coil. With computer managed engines this is not necessary, the computer does the work. Hope this clears up some issues for you. Ava g'day mate. )

Q:A vertical straight wire carrying an upward 14.2 A current exerts an attractive force per unit length of 7.80E-4 N/m on a second parallel wire 7.60 cm away. What is the magnitude of the current that flows in the second wire?

For a current I1 = 14.2 Amperes and radial separation between wires r =0.076 m, the magnetic field at wire 2 is B =0.000037368 Tesla If current I2 = 21 Amperes then the force per meter is F/ΔL =0.000784 Newtons/m hyperphysics.phy-astr.gsu.edu/hba... Goodbye

Q:Which wire is quot;hot, white or black?

Black is hot in AC voltage white is your neutral

Q:Can you swap out a 1984 Porsche 944 wiring harness with a different car's wiring harness? If which car. Thank you.

You can order a new 944 wiring harness, but it is a lot of work. Much easier is to just get a good manual with a wiring diagram, and replace only the damaged wires, splicing at little as possible, as you go. I assume you just have some heat cracked wires, unless you had a fire or something? You can't take the harness from another car because all the connectors are going to be the wrong type, gender, or location. Especially things like the brainbox harness plug, etc.

Q:when i wire these together the light stays on. help

I okorder /

Q:How do you wire a 2 wire smoke detector directly to an alarm (no panel). The terminals are numbered 1,2,3,4 and the instructions say that 1 is for DC+ and 2 is for DC-. How do I wire an alarm so when the detector senses smoke, the alarm goes off? Thank you.

you would have to have a dc transformer, but what it appears that is to be wired into a home sec system. I may be wrong what is 3/4 for?

Q:What's the factors affecting resistance of a wire? and why? thank you!

The 2nd and 3rd discussions were good but didn't discuss magnetism. The 1st guy: an open circuit has infinite resistance. Even a straight piece of wire has some self-inductance (or self-magnetism). One affect of inductance is that it opposes changes in current. So when you first apply a dc voltage across a wire and a dc current starts to flow, the self-inductance will resist the increase in current. It will appear to be because of higher resistance than expected. But the current will increase over a short time, and once it gets to a steady-state, the apparent resistance from the self-inductance is zero. This, self-inductance in a straight piece of wire, is a minor affect compared to components that presumably are in the circuit. After the current reaches steady state, the self-inductance will try to oppose a decrease in current. If the voltage and therefore the current are ac - alternating, this gets more complicated. The current is always trying to change. At the level of study I think you are, you should save this for later.

Q:Are toast - previous owner did a bad amp install on them and there is basically no wire left to use for mine.Is it possible to run a radio power wire/remote wire from the fuse panel back to the radio? If so can i just shove the wire in the fuse holder then stick the fuse back in on top of it?((Fuse 8 is the mustangs radio fuse))

Never wire anything into your fuse box, that will defeat the purpose of having it. You will have to do what's called a hard wire. You will need to run all new wires, which is the safest way to do it, with all proper fusing. A constant +12, a switched +12 and a ground is all you need for the radio to work, and all new speaker wires. If you can find one in a junkyard, you might be able to find a new harness to repair the OEM one, and that would really help you out. Good luck!
