Elektrigeneraatorid are devices that convert mechanical energy into electrical energy. This conversion is typically achieved through electromagnetic induction, where a rotating magnetic field or conductor induces an electric current. The mechanical energy can originate from various sources, including internal combustion engines, steam turbines, water turbines, wind turbines, or even manual cranking.

The fundamental principle behind most electrical generators is Faraday's law of induction. This law states that a changing magnetic flux through a circuit induces an electromotive force (EMF), which drives an electric current. In a generator, this change in magnetic flux is usually accomplished by rotating a coil of wire within a magnetic field or by rotating a magnet near a stationary coil.

Generators are essential components of modern society, providing the electricity needed for homes, businesses, and industries. They range in size from small portable units used for backup power to massive installations in power plants that supply entire regions. The type of generator used depends on the application and the available mechanical energy source. For example, power plants often utilize steam turbines powered by burning fossil fuels or nuclear reactions, while wind farms use wind turbines. Portable generators frequently employ gasoline or diesel engines. The output of a generator can be either alternating current (AC) or direct current (DC), depending on the design and the presence of a commutator or rectifier.
