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.
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.
The copper wire is typically positive. However, the best way to determine which is positive and negative is by referring to the user manual or guide that came with the speakers. The writing on the silver wire is likely there to indicate which wire is positive.
Usually copper, sometimes gold or silver.
Yes
Gold is the most ductile metal among copper, gold, silver, and nickel. It is able to be drawn out into a thin wire without breaking.
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
The copper wire in silver nitrate forms a heterogeneous mixture. In this case, the copper wire does not dissolve in the silver nitrate, so they physically remain as separate substances within the mixture.
Yes; it is tinned copper.
The price of copper today is $3.43 a pound. The price of silver today is $12.90 an ounce. Copper is much cheaper.
When a copper wire is placed in a silver nitrate solution, a redox reaction occurs. Copper atoms from the wire lose electrons to form copper ions in the solution, while silver ions gain electrons to form solid silver. This leads to the deposition of silver metal on the surface of the copper wire.
Speaker cable can have an insulator that could be any color. The wire inside is typically silver, copper or gold colored.
