Background Information Definition of a Generator

• A device that converts mechanical energy to
  electrical energy, using electromagnetic
  induction.

4
Background Information Inventor

• One of the most influential scientists in the
  field of electricity with little formal
  education.
• Discovered the principle of generators and built
  the first electromagnetic generator Faraday
  disc in the 1830s.
• Also discovered diamagnetism and electrolysis.

Michael Faraday 1791 - 1867

Principle of Operation Concept

• Faradays Law states that the great the number of
  turns or the faster the coil is moved through the
  magnetic flux pattern, the greater the induced
  voltage.
• This concept enables us to establish voltages
  with a generator.

Advantages

• In areas where the power supply is intermittent,
  like in Third World Countries, generators can
  provide power.
• Generators also can provide backup power for
  hospitals, shopping malls, etc

Disadvantages

• Gasoline-powered generators require more frequent
  maintenance.
• Diesel-powered generators tend to be noisier and
  more expensive.

Conclusion

• Generators are devices that use a magnet in order
  to induce a flow of electric current in a a
  circuit.
• There are diesel, gasoline, liquefied petroleum
  gas, and propane-powered generators.
• Generators offer a level of safety and security
  when a power supply is unstable.
• Generators also has its disadvantages.
