  2. Quad Cities Nuclear Generating Station - Wikipedia

    en.wikipedia.org/wiki/Quad_Cities_Nuclear...

    Quad Cities Generating Station is a two-unit nuclear power plant located near Cordova, Illinois, United States, on the Mississippi River. The two General Electric boiling water reactors give the plant a total gross electric capacity of approximately 1,880 MW. It was named for the nearby cities of Moline, Illinois, Rock Island, Illinois ...

  3. Polyphase system - Wikipedia

    en.wikipedia.org/wiki/Polyphase_system

    One voltage cycle of a three-phase system. A polyphase system (the term coined by Silvanus Thompson) is a means of distributing alternating-current (AC) electrical power that utilizes more than one AC phase, which refers to the phase offset value (in degrees) between AC in multiple conducting wires; phases may also refer to the corresponding terminals and conductors, as in color codes.

  4. Electronic band structure - Wikipedia

    en.wikipedia.org/wiki/Electronic_band_structure

    Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules. Band theory has been successfully used to explain many physical properties of solids, such as electrical resistivity and optical absorption , and forms the foundation of the ...

  5. Line-of-sight propagation - Wikipedia

    en.wikipedia.org/wiki/Line-of-sight_propagation

    Line of sight (LoS) propagation from an antenna. Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. [1] Electromagnetic transmission includes light emissions traveling in a straight line.

  6. Band offset - Wikipedia

    en.wikipedia.org/wiki/Band_offset

    The band offsets, especially those at heterovalent heterojunctions depend significantly on the distribution of interface charge. The band offsets are determined by two kinds of factors for the interface, the band discontinuities and the built-in potential. These discontinuities are caused by the difference in band gaps of the semiconductors and ...

  7. List of Status Quo members - Wikipedia

    en.wikipedia.org/wiki/List_of_Status_Quo_members

    Status Quo are an English rock band. Formed as The Paladins [1] in 1962 at Sedgehill Comprehensive School, Catford, by schoolboys Francis Rossi, Alan Lancaster, Jess Jaworski and Alan Key. The group has had a career spanning almost 60 years, their current line-up includes consistent member Rossi, keyboardist Andy Bown (official member since ...

  8. Valence and conduction bands - Wikipedia

    en.wikipedia.org/wiki/Valence_and_conduction_bands

    In semiconductors and insulators the two bands are separated by a band gap, while in conductors the bands overlap. A band gap is an energy range in a solid where no electron states can exist due to the quantization of energy. Within the concept of bands, the energy gap between the valence band and the conduction band is the band gap.

  9. Performance and modelling of AC transmission - Wikipedia

    en.wikipedia.org/wiki/Performance_and_modelling...

    Most transmission lines are high-voltage three-phase alternating current (AC), although single phase AC is sometimes used in railway electrification systems. Electricity is transmitted at high voltages (115 kV or above) to reduce the energy loss which occurs in long-distance transmission. Power is usually transmitted through overhead power lines.
