Group 11 element Parkes process. These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver
Theft of electricity a rotating element. Foreign material is placed inside the meter to obstruct the free movement of the disc. A slower rotating disk signals less energy consumption. This type of tampering is done on electronic meter to make it either latent damage or permanent damage. Detection can be done correctly in high end meters only. A number of approaches to detect electricity theft have been proposed. The predominant direction in research and development is employing artificial intelligence, and in particular machine learning methods, to detect customers that steal electricity. "Katiyabaaz" (Powerless), a 2014 Indian documentary film, dealt with issue of power
