  • wireless

    radios in the uk that were not portable continued to be referred to as wireless sets into the 1960s. the term was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires or cables.

  • fly-by-wire

    fly-by-wire fbw is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. the movements of flight controls are converted to electronic signals transmitted by wires hence the fly-by-wire term and flight control computers determine how to move the actuators at each control surface to provide the ordered response.

  • network planning and design

    network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. the process can be tailored according to each new network or service.

  • electrical engineering

    electrical engineering is a technical discipline concerned with the study, design and application of equipment, devices and systems which use electricity, electronics, and emerged as an identified activity in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution and use.

  • electrical telegraphy in the united kingdom

    electrical telegraphy in the united kingdom led the world in the first half of the nineteenth century.telegraphy is the sending of textual messages by human operators using symbolic codes. electrical telegraphy sends these messages over conducting wires, often incorporating a telegram service the delivery of telegraph messages by messenger from the telegraph office .

  • electrical wiring

    electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.. wiring is subject to safety standards for design and installation. allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the .

  • residual-current device

    in the latest guidelines for electrical wiring in residential buildings 2008 handbook, the overall residential wiring need to be protected by a residual current device of sensitivity not exceeding 100 ma. additionally, all power sockets need to be protected by a residual current device of sensitivity not exceeding 30 ma and all equipment in .

  • overhead line

    the auxiliary wire can be of a more conductive but less wear-resistant metal, increasing transmission efficiency. earlier dropper wires provided physical support of the contact wire without joining the catenary and contact wires electrically. modern systems use current-carrying droppers, eliminating the need for separate wires.

  • exploding-bridgewire detonator

    however, they require a bulky power source for the current surges required. the extremely short rise times are usually achieved by discharging a low- inductance , high-capacitance, high-voltage capacitor e.g., oil-filled, mylar-foil, or ceramic through a suitable switch spark gap , thyratron , krytron , etc. into the bridge wire.

  • telegraphy

    most of the early electrical systems required multiple wires ronalds' system was an exception , but the system developed in the united states by morse and vail was a single-wire system. this was the system that first used the soon-to-become-ubiquitous morse code.

  • united states military standard
