    Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

    Class A designs have largely been superseded for audio power amplifiers‚ though some audiophiles believe that Class A gives the best sound quality‚ due to it being operated in as linear a manner as possible. In addition‚ some aficionados prefer thermionic valve (or "tube") designs over transistors‚ for a number of reasons: Tubes are more commonly used in class A designs‚ which have an asymmetrical transfer function. This means that distortion of a sine wave creates both odd- and even-numbered harmonics

    scientific instruments for analyzing specimen surface such as the electron microscope and the Auger electron spectrometer require clean‚ ultrahigh vacuum. The electron microscope and Auger electron spectrometer need fine electron probe‚ requiring a field emission emitter which can well work under ultrahigh vacuum. In the electron microscope and the ion microscope‚ microdischarges due to applying high voltage to electrodes sometime occur‚ resulting in deterioration of image quality. Microdischarges are related
