why is cable called cable

The British pound / U.S. dollar currency pair is one of the oldest and most widely-traded currency pairs in the world. Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable. This causes the voltages induced by a magnetic field between the shield and the core conductor to consist of two nearly equal magnitudes which cancel each other. Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals or power from one device to the other. Cat 5e is currently the most commonly used cable, mainly due to its low production cost and support for speeds faster than Cat 5 cables. Long-distance communication takes place over undersea cables. The term cable is a slang term used by forex traders to refer to the exchange rate between the pound and dollar and is also used to simply refer to the British pound itself.

Three of the principal design techniques are Shielding makes use of the electrical principle of the Coaxial design helps to further reduce low-frequency magnetic transmission and pickup. The offers that appear in this table are from partnerships from which Investopedia receives compensation. Long-distance communication takes place over Physically, an electrical cable is an assembly consisting of one or more conductors with their own insulations and optional screens, individual covering(s), assembly protection and protective covering(s). Cables are used extensively in electronic devices for power and signal circuits. Cable is a term used among forex traders referring to the exchange rate between the U.S. dollar (USD) and the British pound sterling (GBP). Cable-replacement services are still typically less expensive than cable TV, but the gap is eroding. A single Ethernet cable has a maximum distance capacity, meaning the cable has an upper limit as to how long it can be before there is a signal loss (called attenuation). To provide fire protection to a cable, the insulation is treated with fire retardant materials, or non-combustible mineral insulation is used Hybrid optical and electrical cables can be used in wireless outdoor fiber-to-the-antenna (FTTA) applications. The International Currency Market is a market in which participants from around the world buy and sell different currencies, and is facilitated by the foreign exchange, or forex, market. This problem results because the electrical resistance of a long cable affects performance. A twisted pair has two wires of a cable twisted around each other.

The second solution is to route cables away from trouble. By using Investopedia, you accept our This is known as the The first solution to these problems is to keep cable lengths in buildings short since pick up and transmission are essentially proportional to the length of the cable.

Cables are used for a wide range of purposes, and each must be tailored for that purpose. New competitors have emerged, challenging the legacy systems. These cables can be placed in several environments to serve antennas mounted on poles, towers or other structures. Investopedia uses cookies to provide you with a great user experience. Limitations of Ethernet Cables . In this design the foil or mesh shield has a circular cross section and the inner conductor is exactly at its center. In these cables, the optical fibers carry information, and the electrical conductors are used to transmit power. Most of the companies raised monthly rates by $5 or $10 earlier this year. Bunching small wires before concentric stranding adds the most flexibility. Beyond this, there are particular cable designs that minimize electromagnetic pickup and transmission. Where the interfering signal has a wavelength that is long compared to the pitch of the twisted pair, alternate lengths of wires develop opposing voltages, tending to cancel the effect of the interference. Cable (or the cable) is a foreign exchange term used for the GBP/USD currency pair rate (British pound priced in US dollars).. Local safety regulations may apply. Electrical cables may be made more flexible by stranding the wires.
