Generators convert mechanical energy into electrical energy using Faraday's law of electromagnetic induction. When a coil rotates in a magnetic field, it induces an electromotive force (EMF) in the coil. Generators can be AC or DC, and the mechanical input can come from engines, turbines, windmills, or human power. Main types of engine generators are standby, portable, and commercial generators. Standby generators automatically provide backup power when electricity is lost, portable generators are transportable for use where no power exists, and commercial generators keep businesses running during outages or provide extra power.

- 3. 1.Introduction to Generators The device which converts mechanical energy to electrical energy is called generator GENERATOR ELECTRICAL ENERGYMEHANICAL ENERGY
- 4. 2.Principle of working: In generators mechanical energy is transformed into electrical energy. A generator has two main parts: Coil Magnet Generator works on Faraday’s law
- 5. 2.Principle of working: Generator works on Faraday’s law of electromagnetic induction. When coil is rotated in a magnetic field by some mechanical means magnetic flux is changed through the coil and consequently EMF is induced in the coil.
- 6. 4.Types of Generators: According to output generators are of two types AC generators and DC generators. According to mechanical work input generators can also be classified. As engine generators , human powered generators , turbine generators and wind mill generators.
- 7. Types of Generators: Mainly used generators are engine generators. They use engine, which provides mechanical energy by use of chemical energy provided by different chemicals as Gasoline, Propane, Diesel fuel and Natural gas. They can further be classified into 3 main types. 1.Standby Generators 2.Portable Generators 3.Commertial Generators
- 8. Standby Generators: These are large, often permanent units often stationed outside a building and like to provide backup power in case the in electricity switches off. They can sense when a power interruption has occurred and automatically start to provide emergency power
- 9. Portable Generators: These generators are designed to be transported whether on cart trailer or by hand where there is no utility of power. They are capable of providing up to 1000 kilowatts of power. They use either diesel natural gas , gasoline or propane as fuel
- 10. Commercial Generators: Commercial Backup Generators keep businesses operating even after the utility power goes out Generators can also be set up to provide additional power.
