2026 EEE Oklahoma State Final - Study Answer Collection Wire - answer - Single conductor, which material is most commonly being copper or aluminum. Cable - answer - Two or more insulated wires wrapped in one jacket. 1.) Twisted pair cable 2.) Multi conductor cable 3.) Coaxial cable 4.) Fiber optic cable - answer - Types of Electrical Cable Twisted Pair Cable - answer - It has two cables that are twisted across each other. Twisting can avoid noise that produced by magnetic coupling, so this type of cable is best suited for carrying signals. It is generally used in telecommunication and data communication. Multi conductor cable - answer - It has two or more conductors that are insulated from each other. Their purpose is to protect signal integrity by reducing hum, noise and crosstalk. Applications include computers, communications, instrumentation, sound, control, audio, and data transmission. Both this and twisted pair cables are called balanced line configuration cables. Coaxial cable - answer - It is composed of an inner solid conductor surrounded by a paralleled outer foil conductor that is protected by an insulating layer. The two conductors are separated from each other by an insulating dielectric. These are generally used in TV Cable. It is called an unbalanced line as the signal on the two conductors is not same, which result in interference but the performance is more stable than a twisted pair cable. Fiber optic cable - answer - It has a much greater bandwidth than metal cables, which means they can carry more data. This kind of cable transmits signals by a bundle of glass threads. They are also less susceptible to interference. For these two reasons, these are increasingly being used instead of traditional copper cables despite that they are expensive. 1.) Solid wire 2.) Stranded wire - answer - Types of electrical wire Solid wire - answer - It is a single conductor that is either bare or insulated by a protective-colored sheath. It offers low resistance and are perfect for use in higher frequencies. Stranded wire - answer - It consists of thin strands of wires twisted together in a sheath. These are more flexible and have larger cross-sectional area than solid wires for the same current carrying capacity. American Wire Gauge (AWG) system - answer - Aircraft wire is measured by the ______, with the larger numbers representing the smaller wires. American Wire Gauge (AWG) system - answer - Used to describe stranded wire. American Wire Gauge (AWG) system - answer - The _____ of a stranded wire represents the sum of the crosssectional areas of the individual strands; the gaps between strands are not counted. When made with circular strands, these gaps occupy about 25% of the wire area, thus requiring the overall bundle diameter to be about 13% larger than a solid wire of equal gauge. overall awg size AWG number of strands/awg size of strand (e.g. 22 AWG 7/30) - answer - How are stranded wires specified? 22-gauge wire, which has a diameter of about 0.025 inch - answer - The smallest size wire normally used in aircraft. Typically of the 0000, or 4-aught size, and have a diameter of about 0.52 inch - answer - Wire size of conductors carrying large amounts of current? Circular Mil - answer - The standard measurement of a round conductor's cross-sectional area. 0.001 inches or 1/1000 inches (0.125 inches is expressed as 125 mils) - answer - One mil is equal to? Square the conductor's diameter - answer - How to find the cross-sectional area of a round conductor in circular mils? Square mil - answer - The unit of measure for square or rectangular conductors such as bus bars. Multiply the conductor's thickness by its width - answer - How to determine the cross-sectional area of such a conductor in square mils? 0.7854 - answer - One circular mil is ____ of one square mil. 12 to 15-inches intervals - answer - Identification markings should be placed at each end of the wire and at ______ along the length of the
