The cable began operating in May 1991, and has a capacity of 675 megawatts. [1] [4] In 2014, the cable was damaged by an anchor from a boat. [6] [7] [8] The incident caused roughly 66,000 gallons of cable insulation fluid to be released into Hempstead Harbor. As of 2021, there are proposals to upgrade the cable in order to increase its capacity ...
The electrical length of an antenna, like a transmission line, is its length in wavelengths of the current on the antenna at the operating frequency. [1] [12] [13] [4]: p.91–104 An antenna's resonant frequency, radiation pattern, and driving point impedance depend not on its physical length but on its electrical length. [14]
In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...
Wire gauges may be broadly divided into two groups, the empirical and the geometric. The first includes all the older gauge measurements, notably the Birmingham gauge (B.W.G. or Stubs) and the Lancashire. The origin of the B.W.G. is obscure. The numbers of wire were in common use earlier than 1735 when the measurements were officially defined. [1]
WMLW-TV (channel 49) is an independent television station licensed to Racine, Wisconsin, United States, serving the Milwaukee area. It is owned by Weigel Broadcasting alongside CBS affiliate WDJT-TV (channel 58) and two low-power stations: Telemundo affiliate WYTU-LD (channel 63, which is simulcast over WMLW-TV's fourth digital subchannel) and Class A MeTV owned-and-operated station WBME-CD ...
In practice, this is hardly possible at high winding speeds since, e.g., at 18.000 windings per minute, the wire guide for a wire with a thickness of 0.3 mm would need to perform a winding pitch in only 0.7 ms. The problem is amplified by the fact that in practice the ideal wire is never absolutely straight.
Often random wire antennas are also (inaccurately) referred to as long-wire antennas.There is no accepted minimum size, but actual long-wire antennas must be greater than at least a quarter-wavelength ( 1 / 4 λ) or perhaps greater than a half ( 1 / 2 λ) at the frequency the long wire antenna is used for, and even a half-wave may only be considered "long-ish" rather than "truly ...
The ideal speaker wire has no resistance, capacitance, or inductance. The shorter and thicker a wire is, the lower is its resistance, as the electrical resistance of a wire is proportional to its length and inversely proportional to its cross-sectional area (except superconductors). The wire's resistance has the greatest effect on its performance.
