 * WHAT IS IT?**
 * An electrical generator is a device that generates electricity from mechanical energy, usually through electromagnetic induction. Electromagnetic induction works by forcibly moving a loop of wire around a stationary bar (a stator) that provides an electric  field, either through a permanent magn[[image:http://electron9.phys.utk.edu/phys136d/modules/m8/images/gen.gif width="310" height="219" align="right"]]et or an electromagnet.

· Crank- rotates the armature · Brush- current leaves the generator through it · Slip Ring- attached to the armature, and through them the current is carried to the brushes · Armature- loop of wire that gets a current induced into it when it rotates in a magnetic field · Magnets- placed by the armature and their magnetic field induces an electric current into the rotating armature
 * PARTS OF A GENERATOR**


 * HOW DOES A GENERATOR WORK (IMAGE BELOW)**
 * In most of the generators, the machanical energy (in this case water/river) turns the turbine.
 * The turbine is attached to the armature, as the turbine rotates the armature rotates with it, this movment current.
 * While the armature is rotateing and producing energy, the Transportashon lines transport it to many places (Homes and Businesses)
 * Another way you can create energy is my a windmill. The wind pushes its blades which is Kinetic energy and their it is transformed into electrical energy.
 * ENERGY CONVERSIONS**
 * An electric generator converts mechanical energy to electrical energy which is done by a motor that is similar to a generator. A generator forces electrons to flow through the external electrical circuit. It is similar to the act of pumping water, which creates a flow of water but does not create the water inside. The source of this energy may be a turbine steam engine, water falling through a turbine and others.


 * An electric conductor, like a copper wire, is moved through a magnetic field. Then, electric current will flow in the conductor, s o the mechanical energy of the moving wire is converted into electric energy.


 * DIFFRENT TYPES OF A GENERATOR**
 * There are two different types of a Generators, AC Generator and DC Generator. A AC Generator is a generator that creates only creates alternating current, in other word a current that moves back and forth. A DC generator only creates direct current.
 * The most common types of Generate found are AC Generators.
 * A AC Generator creates a AC current because as the armature rotates the direction of the current in the armaturechanges directions, fist it was going up and then down. this creates a negative adn posative current, their for, the current alternates.


 * DIFFRENT CRANKS **
 * In diffrent places their are diffretn cranks, in other words, in diffrent places their are other things that move the turbine.
 * Windmill: Wind moves the blades of the windmill
 * Turbines (rivers): Water/Dam moves the Turbine
 * Hot Places: The steam from the group.
 * Nuclear Power Plants: the nuclear reaction or the atoms of unearium creat heat that produce steam from the cooling down that moves the tutbine.
