Speaker wire is a passive electrical component described by its electrical impedance, Z.The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance.
Long loops, such as those terminating at more than 18,000 feet (5.49 kilometres) from the central office, pose electrical challenges. When the subscriber goes off-hook, a cable pair behaves like a single loop inductance coil with a -48 V dc potential and an Electric current of between 20–50 mA dc. Electric current values vary with cable ...
TOSLINK (Toshiba Link) [3] is a standardized [4] optical fiber connector system. [5] Generically known as optical audio, the most common use of the TOSLINK optical fiber connector is in consumer audio equipment in which the digital optical socket carries (transmits) a stream of digital audio signals from audio equipment (CD player, DVD player, Digital Audio Tape recorder, computer, video game ...
That means the capacitive reactance is about 80Kohms per foot at 20 KHz. So let's take a 20 foot (rather long) speaker cable. That means that the total capacitive reactance of the cable is about 4 KOhms. The output impedance of a transistorized amplifier is something less than an ohm, but let's take a hypothetical 16 Ohm tube amp instead.
Zip-cord is a type of electrical cable with two or more conductors held together by an insulating jacket that can be easily separated simply by pulling apart. In Australia it is known as 'figure-8' cable. [1] The zip-cord term is also used with optical fiber cables consisting of two optical fibers joined in a similar manner.
A Cat 6 patch cable, terminated with 8P8C modular connectors. Category 6 cable (Cat 6) is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat 6 must meet more stringent specifications for crosstalk and system noise than Cat 5 and ...
