Most uses for coaxial cable involve transmission of AC/RF signals. The outermost conductor is usually referred to as the "Shield" or "Ground Shield" and is connected to ground potential, while the inner conductor(s) carry the signal(s). The outermost conductor is usually thought of as being at 0 volts, while the AC signal on the inner wire transitions around it in both positive and negative. The terms Positive and Negative have little meaning as regards the AC signals but in some satellite applications, particularly the 18" dish variety, a DC "offset" is applied to the cable to power the Low Noise Block Down Converter (LNB) on the dish, and also varying the amount of the offset between 12 and 18 volts DC to select signal polarization. In this case, the outermost conductor would be negative, and the innermost would be positive regarding the DC offset.
I had this same problem. I had mixed up the wires on one of the speakers and the system was turning itself off to keep from overloading. Make sure your negative wires are going to the negative output on the system.
To calculate the cross sectional area (CSA) of a cable, you have to use a micrometer to verify its diameter, then divide the diameter by two to get the radius (r). With the radius we can calculate the CSA of the cable.CSA = pi x r2 (Applicable to solid wires only).For example:If a cable is 0.5 cm in diameter, its radius is 0.25 cm.CSA = 0.196349541 cm2You will need to decide to how many decimal places it is appropriate to quote your answer.

In electrical wiring awg ( American wire gauge) goes to 4/0 as the largest size. then it goes to 250 mcn. MCN which stands for 1,000 Circular Mils. this system uses the cross sectional area of the wire as a measurement. typical mcm wire sizes start at 250 and go to 300,350,400,500,600, etc. 250 mcm is usually good for a 200 amp service in aluminum wire in Canada per code. American standards are not as high or as good as Canadian ones. 250 MCM Welding cable is the next size larger than the standard 4/0 cables used on most standard mag particle inspection machines. Increasing the cable size will reduce the heating effect on the cables and increase the available current. welding cables is one of the more common uses for bigger sized wires. 250 MCM Cable has a cross-sectional area of .199 square inches

how many wires does a coaxial cable have
A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other. Since they have a common center, or axis, they are called "coaxial" (co-axial).A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other.

The red wire and terminal on a 2008 Honda Civic are the positive wires for the battery. The black wires and terminal is the negative battery cable.
The negative cable actually is bolted to the engine block, and the positive cable will go to the solenoid that is attached to the radiator support. On newer models, the solenoid would be attached to the starter, and then, of course, the positive cable would connect at the solenoid down below on the starter.
You can get the positive and negative wires for a class project at a store that sells the Physics apparatus.
The cables that do that are HDMI, Displayport or coaxial cable (antenna) wires.
DSL is transmitted through telephone wires and is much faster than cable internet. Cable internet is sent through coaxial wires and uses frequencies to transmit.
All electrical components have positive and negative wires to complete the circuit.
No. Coaxial cable is a single wire that has a thick coating around it. A common use of coaxial cable is for cable television. This is the cable that goes from the jack on the wall into your cable box. Twisted pair contains multiple cables which are split into pairs and twisted together. CAT5/CAT5e/CAT6 cable are all examples of twisted pair. There are a total of 8 wires inside. Every two wires are twisted together to form a pair. The purpose of the cables being twisted together is to reduce electrical interference between the wires.
