Q:ok so i wired the subs to the amp now, the positive (Red) goes to the battery, the ground (Black) is currently grounded to the metal under my drivers seat. My question is does it matter the color wire is that goes to the stereo? Can i use a red or black? Does it really matter? If not, where exactly would i hook it up behind my aftermarket sony headunit?

If your talking about a remote wire there should be a blue wire with a white stripe coming out of the wiring harness for your receiver/head unit... And run a wire from that to the remote terminal on your amp. All this does is send a 12v signal so when you turn the key on your car/truck it signals the amp to turn on. If your head unit does not have a remote wire you can run a wire from your amp to your ignition..

Q:The resistivity of a 18.0 m long wire is 3.76E-8 Ω.m and its cross sectional area is 6.52E-6 m2. If the wire carries a current of 1.44 A, what is the voltage across the wire?

R = ( rho x l)/A Where: R is the resistance, rho the resistivity, l the length and A the area Resiatance of wire = (3.76 x 10^-8 x 18)/6.52 x 10^-6 R = 0.1038 Ohms Voltage across wire = current through wire x resistance of wire V = I x R V = 1.44 x 0.1038 V = 0.14947 V = 0.15 Volts

Q:who knows the use of wire mesh? Actually where does the wire mesh be used?

well different uses for different sizes and material of the wire. i have a stainless steel one in kitchen to make fries. the iron one is used on windows. people use it to make pet - bird and animal cages as well

Q:circuit breakers,equipment,wire,or people

A fuse protects wire from an overload of ampacity, this can prevent fires and it prevents shorts in the system as well. So if you have a short it protects the equipment as well as wire but it can protect people from fires if there is short and a fire. so in essence of your question it protects all of the above in way or another. Some breakers in some cases are protected by a fuse such as in motor or motor controls as well. There are several different type of fuses in the feid today form ow voltage to high voltage fuses and different types too.

Q:During a lab experiment, a straight piece of copper wire is connected across the terminals of an AC generator and the current through the wire was measured. If the wire is removed and a part of it is tightly wound into a loop of many coils and the wire is then reconnected to the generator, will the measured current through the wire be greater, lesser, or the same as it was before the wire was coiled? Explain your answer.

Assuming the generator output voltage (RMS) remains constant the current will be less through the coil. By wrapping the wire into a coil it's resistance doesn't change but it's self inductance increases. AC in a wire produces an alternating (changing) magnetic field that is concentrated into a smaller space as a coil - so increasing it's strength and ability to link with the wire that produced it. When this changing magnetic field links (passes through) it's 'own' coils a self-induced 'back' EMF(voltage) is generated in the wire that opposes the 'forward' current from the generator (Lenz's law). If the geverator provides a pd = Vg and the back EMF = Vb, then the current in the coil is effectively being driven by a reduced pd = (Vg - Vb) .

Q:currently I have 2 12woofers wired to a single amp with 2 gauge wiring. Will it make a noticable difference if I upgrade the wiring to 0 gauge?

No. Even if the wire is undersized there would have had to have been a LOT of voltage drop in the 2 awg compared to the 1/0 awg wire, AND the amp would have to be loosely regulated for there to be any significant improvement. If both of those things are true it's still not likely there'd be enough of a change to be audible.

Q:The new light has 1 live, 1 neutral 1 earth wire, do i remove the earth connect the reds if so what about the 2 blacks?

No! Wire the new light exactly like the light that you removed. If you don't remember what wire went where on the old light then you made a mistake by removing the old one without marking the wires or at least taking a cell phone picture or something. It sounds like there is probably more than one light fixture being controlled by that switch. It's hard to tell by your description. Electrons don't flow by wire color. There is no way to really tell what is going on by naming colors. Come back on here when you have a better description of what is going on. How many lights come on when you flip that switch? Is there more than one switch that controls that fixture? Which wires were hooked to the old light? Are any of the wires still wire nutted together? Don't be experimenting by hooking that earth ground wire to any other wire. Leave it hooked to the ground lug on the box. It has nothing to do with the light operating. It's for safety.

Q:Found some electrical wiring resonably priced on craigslist but it says -----8 gauge (AWG), 3 wire, direct burry electrical cableDOES THAT MEAN ITS 3/0 WIRE? Because I need 3/0 wire direct burriedI am looking to buy some extra 3/0 wire and found some on craigslist for a reasonable price..

8gauge 3 wire means exactly what it says. you will be getting a number 8 cable with 3 wires in it...the best thing to do is dig the trench put the wires in conduit and use 3/0 wire..Will last years longer and you probaly will not have to dig your trench back up in a few years.

Q:Replacing my 3 prong dryer outlet but there is a blk, red, wht, and a bare wire in the box. I know where the colored ones go on the outlet but what do I do with the bare one? I didn't remove the old one so I don't know how the old 3 prong outlet was wired with these wires. Thanks.

4 wires means you need a matching 4 wire receptacle.* Black and red go to L1 L2, the white to N and the bare wire goes to the green screw. If the wall box is metal the ground needs to attach there as well. Then replace the cord on the dryer to match that configuration. Most dryers are 220/240 volt 30 amps. * Now you are in compliance with current National Electric Code standards and your insurance company will thank you. (well not really, but it sounds good)

Q:I need the wiring diagram for the 1992 Lexus ES300 OE Stereo.I specifically need to know what colors (or numbers) the wires are for the front right and front left bottom door speaker.

ur best bet is to take off the door cover and look at the speaker and go off the colors u see going into the speaker
