Why is it beneficial to twist insulated copper wires rather than run them side by side as in twisted-pair cables?

* As a general rule, the chief advantage of twisted pairs is that signals do not couple so much between pairs if they are twisted. * If you are transmitting balanced signals (as when using emitter-coupled logic for instance) the balance is maintained from source to sink. * By controlling the number of twists per inch you can establish a known characteristic impedance for the pair. Again, when using ECL or similar, matching the line to the logic avoids "impedance bumps" which cause reflections.

How can I fix my Audio Cables on my headphones?
My PC speaker cables have a copper wire, as well as a insulated (white) copper wire. The headphones (Sony) appear to have 3 wires in them - green, red, and orange. The links you posted are more for car/home theater speaker wire.
What are some types of low voltage cables?
Below 24 volts: low voltage cables are like other cables but without so much insulation. They are made of copper and insulated with pvc, usually only one layer. They are most commonly used in cars.
What Is a metal string that brings electricity to our house?
Electricity is brought into our homes along cables of conductive copper wires insulated against shortening by an insulating covering of plastic.
Is a copper wire a ground wire?
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
How big around is copper wire mcm 750?
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
What kind of wire is in PC ribbon cables?
Computer cables are often made of copper.
What is the element that is used for eletrical cables?
copper
What are copper supplements used for?
Copper supplements may be beneficial in treating or preventing copper deficiency.
What happens if the insulation is removed from the copper insulated magnet wire?
No it does not attract to magnets
Why does copper wire have to be insulated?
To stop the conductor from touching adjacent grounded structures.
Booster cables - what is the difference in use between copper cald aluminum and 100 copper wire?
It depends on some factors which are not mentioned in the question. The main difference between 100% copper wire and copper clad aluminum is that IF they are the same diameter, then the copper will carry and stand up to more electrical current than the aluminum. If the diameter of the aluminum cables have been upgraded in size, to match the current carrying capacity of the normal copper cables, then the only remaining difference is that copper withstands much more bending and coiling beforethe metal begins to "work harden," and some of the individual wire strands begin to break. In other words, the copper stands up to use better than aluminum. When buying booster cables, read the lables, and make sure that the maximum number of Amps, for which the aluminum cables are capable of carrying, is equal to or greater than the highest rated copper cables. Therefore, IF the copper clad aluminum cables are rated for the same current carrying capacity as copper cables, then there is NO difference in use between the two types.
