A VGA cable is a lead used for transmitting video signals, and it is most commonly used to link computers with monitors. Some high definition televisions use this type ofcable as well. VGA stands for video graphics array, and it was a graphics standard used by IBM in its early PCs sold in the 1980s. In addition to computers, VGA cables can be used with some games consoles, allowing them to be used with a computer monitor, which may offer a better quality picture than older cathode ray televisions, particularly for games that have fine detail or small text. Some high definition television sets have a VGA input, and there is a great debate about whether an analog signal carried by a video cable can offer picture quality as good as the digital signal carried through methods such as HDMI. The relatively low price of a VGA cable means this option may be worth trying out before people decide to switch the screen or input device to models that carry digital signals. |

28AWG | 7 / 0.127 | 0.93 ± 0.05 | 0.80 ± 0.05 | 0.80 ± 0.05 | 85% | 5.50 ± 0.15 |
Physical Construction Description:
One 28AWG pair and two 28AWG conductors are cabled
together with an aluminum/PET tape and an overall braid
shield with 85% coverage. A PVC jacket is then applied with
an overall OD of 0.17"±0.02". Standard jacket color is light
grey, but black is also available. The conductors and pairs are
color coded for ease of identification. USB Cables are
available in various constructions.

Speaker wire is used to make the electrical connection between loudspeakers and audio amplifiers. Modern speaker wire consists of two electrical conductors individually insulated by plastic. Certain older designs also featured another pair of wires for a powered line to power an electromagnet in the loudspeaker before permanent magnets became economical to produce and use.The effect ofspeaker wire upon the signal it carries has been a much-debated topic in the audiophile and high fidelity worlds.
Speaker wire, like any other linear electrical component, has three parameters which determine its performance: resistance, capacitance, and inductance. If a perfect wire were possible, it would have no resistance, no capacitance, and no inductance. The shorter a wire is, the closer it comes to being perfect, as resistance decreases as length decreases in all conductors (except superconductors). Resistance is the property which has the most effect on speaker wire performance, whereas capacitative and inductive characteristics of speaker wire are insignificantly small relative to the loudspeaker itself. Larger conductors (smaller wire gauge) have smaller resistance. As long as speaker wire resistance is kept to less than 5% of the speaker's impedance, the conductor will be adequate for home use. Stranded speaker wire is more flexible than solid wire, and is suitable for movable equipment. Even with poor-quality wire, an audible degradation of sound may not exist. Many supposedly audible differences in speaker wire can be attributed to listener bias or the placebo effect. |
