Introduction
In simple words; an electric generator can be defined as a device that works by converting mechanical energy into electrical energy. So basically, a generator is an opposite of a motor. The generators date back to 1827 when Hungarian Anyos Jedlik came up with what is now known as Jedlik Dynamo.
How Does a Generator Work?
An electric generator’s working principle is the opposite of that of an electric motor. The inverter generator forces the electricity into flowing through an external circuit. The source of mechanical energy may vary from turbine steam engine to wind turbine. In simple words, electric generators can be defined as coils of electric conductors generally made of copper wire wounded tightly across a metal core and mounted in order to spin inside an array of big magnets. The movement of electric conductor results in flow of electrical current. The movement is achieved by a mechanical power source.
Types of Generators

Precautionary Measures
- Beware of moisture.
- Make sure generator is placed at a place with good ventilation.
- Learn how to switch it off in case of emergency.
- Don’t overload the generator.
- Make sure it is on a level surface before running it.
- Make sure the generator is grounded.
