It doesn't really matter, as long as you connect them to the same polarity at both ends. Most people use the gold or reddish-copper wire as the positive, as it is the red terminal and the silver, or non-colored lead to the negative as it is black.
Copper wire I think would be the black wire
Whichever one you connect to the positive terminal. The colors are there so you can find the same wire at the other end.
Yes; it is tinned copper.
No. Ni-Chrome wire is resistance wire used in pottery and as a heating element for pyrotechnics. There is no application for Home Theater for this wire.
GOLD IS USUALLY THE + HOWEVER, IF YOU ARE LOOKING ONLY AT ONE END, YOU BETTER CHECK THE OTHER END AND MAKE SURE IF YOU ARE ATTACHING BOTH ENDS AS PART OF THE SAME INSTALLATION, IT WILL NOT REALLY MATTER OTHER THAN GOING ALONG WITH THE INDUSTRY STANDARD JUST MAKE SURE IT GETS CONNECTED: + TO + and - TO -
The new speakers come with un-stripped copper wires..... you need a pair of wire strippers.... i put in kenwood speakers and the size of the wire was 14 somethin. you would need to get a wire diagram for you car/truck to see the colors of the positive and negative wires. then look on the aftermarket speaker box to see which wire is negative and which one is positive.... After you would do all this, just match up negative to negative and positive to positive. simple as that. I'd recommend wire nutting the wires or electrical taping them... but DO NOT put all four wires together. that will mess your speakers' sound up completely. wire nut the positives together and then wire nut the negatives together.
It is traditional to use the copper colored wire as the positive. Of course, the electrons don't care what color the wire is as long as you hook it up the same at both ends!
Yes
Usually copper, sometimes gold or silver.
All three are very good conductors.Copper is relatively inexpensive, while gold and silver are very expensive.Copper and silver oxidize slowly to a conductive oxide, gold does not oxidize or corrodeConsidering the above copper is generally the best choice for electrical wire unless corrosion is a potentially serious problem, in which case a very thin gold plating on copper wire may be a reasonable choice.
Whichever one you connect to the positive terminal. The colors are there so you can find the same wire at the other end.
copper is positive
Yes; it is tinned copper.
When you place copper wire in a silver nitrate solution, your result should be a heterogeneous mixture.
The price of copper today is $3.43 a pound. The price of silver today is $12.90 an ounce. Copper is much cheaper.
Electrical wire can consist of several different elements from Aluminum to copper and even steel. Many types of wire have been made from silver and also gold, depending on the application, and it's no uncommon to plate the wire with another metal to avoid corrosion or rust.
Speaker cable can have an insulator that could be any color. The wire inside is typically silver, copper or gold colored.
It doesn't matter both wires are made of copper. The only difference in colour is to keep the polarity the same throughout the system. Pick which colour you want to make positive and use it on all of the positive terminals.
