Phillip Hagar Smith (April 29, 1905 – August 29, 1987) was an American electrical engineer, who became famous for his invention of the Smith chart.. Smith was born in Lexington, Massachusetts in 1905, and graduated from Tufts College in 1928 with a BS degree in electrical engineering.
The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart) is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio ...
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
Electrical engineers typically possess an academic degree with a major in electrical engineering, electronics engineering, electrical engineering technology, [89] or electrical and electronic engineering. [90] [91] The same fundamental principles are taught in all programs, though emphasis may vary according to title.
Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).
Figure 2.1. Circuit diagram of a ladder network low-pass filter: a two-element-kind network. Comprehensive cataloguing of network graphs as they apply to electrical circuits began with Percy MacMahon in 1891 (with an engineer-friendly article in The Electrician in 1892) who limited his survey to series and parallel combinations. MacMahon called ...
Casual use in an engineering class has been cited as evidence of the sexism faced by women in scientific fields. [15] Latanya Arvette Sweeney, associate professor of computer science at Carnegie Mellon, mentions yet another as one reason why she felt alienated and eventually dropped out of MIT in the 1980s to form her own software company.
