generator

Physics

Any machine that converts mechanical power into electrical power. Electromagnetic generators are the main source of electricity and may be driven by steam turbines, water turbines, internal-combustion engines, windmills, or by some moving part of any other machine. In power stations, generators produce alternating current and are often called alternators.

Mathematics

See cone, cylinder.

Chemical Engineering

A machine used to produce electrical power. Electromagnetic generators are widely used to produce electrical power and are driven by water turbines, steam turbines, internal combustion engines, windmills, or other forms of mechanical energy. In power stations, generators produce alternating current (a.c. current) and are also known as alternators.

Computer

1. A program that accepts the definition of an operation that is to be accomplished, and automatically constructs a program for the purpose. The earliest example of this kind of program was the sort generator, which took a specification of the file format and the sorted order required, and produced a sorting program. This was followed by report generators, which constructed programs to print reports from files containing information in a specified format. The best-known program of this kind is RPG II. See also application generator.
2. An element g of a group G with the property that the various powers
$g^{0}, g^{1}, g^{2}, \dots$
ultimately include all the elements of G. Such a group is said to be a cyclic group; it is also an abelian group. Generators can also be defined for monoids in a similar way.
The set of generators S of a group G is a subset of G having the property that every element of G can be expressed as a combination of elements of S. See also group graph.

Electronics and Electrical Engineering

A machine that converts mechanical energy into electrical energy. An electromagnetic generator (i.e. a dynamo) has a coil that is made to move so as to cut lines of magnetic flux. An electrostatic generator, such as a Van de Graaff generator, has equal and opposite electric charges produced by electrostatic induction or friction; mechanical energy is then used to separate the charges. See also alternating-current generator.
