Q:Why does a thin wire melt and a thick wire glow when put up to the terminals? Explain in terms of resistance and current. Thanks=]

Everything has a temperature at which it will melt. Every conductor also has a resistance, which is just like it sounds, a wire sort of resists the electricity passing through it by heating itself up. If a wire's resistance causes it to heat up so much that it melts, either the wire is too thin, or there is too much current passing through it, or both. A thicker wire can handle the same current without heating up so much that it melts. Sorry I don't have any formulas for you, but I think you should understand it now.

Q:what wires are my speaker wires going to and coming from the factory amp and how do i hook them up please help i drive a 96' ford exploder

Q:I needed a new tail light for my trailer. The aftermarket tail lights only came with two wires sticking out the back, one red and one black. The stock tail light that broke had 3 wires and so does the harness on the trailer end. People have told me that even though it is different it will work. Do I join the two hot wires together with the red wire and then the return wire to the black? There is no wiring diagram avalible and I dont have the money to replace then entire lighting system. Thanks for your help.

Pull the lens and look at the bulb. If it is a 2 element bulb then it will work, if it is a single element it will not. If it is a 2 element then one of the wires is turn and stop light and the other is tail light. It will use a body ground in that case. On your trailer harness you will have a brown wire, that is tail lights, the turn and stop light (same wire) will be either green or yellow depending on what side of the trailer you are on. The white wire is ground. The turn and stop light will be much brighter than the tail light so just twist the wires together and see which is which. You can hook the white wire to the mounting screw of the light fixture to be sure you have a good ground.

Q:need to know how to properly wire this amp in a truck

wow I have never heard of this amp until u mentioned it. the ratings seem good. ur best option would be to call sonic electronics have them send you a manual on how to wire this amp. they sell this amp. I mean u ask how to properly wire it. wire it to get power ? or to the woofers ? red wire + goes to your battery. black wire - goes to your ground (not your battery) to the frame of ur vehicle. then u need a blue wire, your remote this wire goes to ur stereo's remote wire it should be the same color or it will be marked. but if u do not know how to hook up an amplifier u should go to a professional shop due to the fact if u improperly hook ur amp up YOU CAN START A FIRE IN YOUR CAR.

Q:does anyone know what wires go on which post on a 1995 chevy lumina 3.1 starter? it was off when i bought the car and im lost. i cant find a straight answer anywhere. a picture of the wiring in question is an instant best answer lol

the small wire goes to the inside / right side pole everything else go to the big post

Q:I have a very old house. I was unhooking the fluorescent light in our kitchen to put a round ceiling light in and the old fluorescent light was plugged into the ceiling (like any regular two pronged electrical plug). How do I wire the ground wire, the line voltage wire, and the neutral wire from the new light so I can plug it into the plug in my ceiling?

I would remove the outlet and wire the light with the wiring powering your outlet. Black to black, white to white and ground to ground. Just like you would have if the outlet weren't there.

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 removed the thermostat before marking the wires and I need to know if anyone knows which wires go where?

Hello Kaitlin: It depends on what wires come from the furnace. You will need to go to the furnace and look at the wires. If it is a gas furnace (with air cond.), there should be a R terminal with a red wire attached this is the power line. The W terminal (heat) has a white wire attached. The G terminal (fan) should have a green wire. The C (common) terminal may have a blue or black wire (or not). The Y (cooling) terminal may have a yellow wire. If it is a heat pump, the wires will be R (power), Y (compressor), O or B (reversing valve), G (fan), C (common), the backup heat has different designations, from W2 to Aux, others. There should be a legend on the furnace to assist. Good luck.

Q:How do I find the remote wire on the back of my stock Ford Focus strereo? I have a line output converter to connect the rca cables to the deck, but I cannot tell wich wire is the remote wire. How can I track this wire down to connect it to the amp?

usually stock decks wont have a remote wire for an aftermarket amp but if you have a power antenna you can use the same wire that turns that on

Q:How could you relate greater wire length resulting in greater resistivity to the context of home

Greater wire length will certainly give you a higher resistance. Since heat is measured in watts, and watts (W) =I^2R, where I=Current and R= resistance, then if you double the resistance of a wire (by making it twice as long) you also double the ammount of watts lost in the wire. Since watts equates to heat, this ammount of heat will make the wire hotter. If you use an extension lead, and wind it round a drum, it can get very hot indeed.
