Figure 3.4 An elementary Metal slip rings alternating current generator. A loop of wire is forced to rotate in Carbon a magnetic field. The induced brush alternating current enters the external circuit through contacts (carbon brushes) that rub against rotating metal rings, called slip rings, attached to the coil The current generated 1, reverses in direction as the coil rotates right hand rule left hand rule The current induced in the coils according to the faraday law interacts with the magnetic field to resist the motion of the coils through the field Therefore it takes energy from some external source to force the rotation

Most electric power plants have the rotating coils of the generator mechanically connected to steam turbines or to water-driven hydroelectric turbines at large dams. The main components of a typical electric power plant are shown in the figure below fly ash high temp. t Turbine LA Generator and pressure Figure 3.3 a diagram of a Bottom ash, cinders pressure Exhaust steam low temperature fuel-burning electric power and pressure plant.
