Definition - What does Electric Generator mean?
An Electric Generator is a device used to generate electricity by converting mechanical energy into electrical energy to be used in external circuit. It is an essential device used to supply the electrical power at the time of power outage and offers continuity of daily activities or various business operations. The generators are designed with different physical and electrical configurations to be used in different appliances. The reverse conversion, i.e., the conversion of electrical energy to mechanical energy is carried out by an electric motor.
Petropedia explains Electric Generator
It is essential to understand that the Electrical Generator does not create electrical energy, but it uses mechanical energy which is supplied to it to force the movement of the electric charges present in the wire of its windings via an external electric circuit. The flow of these electric charges contains the output electric current that is supplied by the generator. To understand this mechanism, the generator is considered to be analogous to a water pump that causes flow of water but does not create the water which is flowing through it.
