What is Generator?
A generator is a device which converts mechanical energy in direct current or alternating current, where the elector moves in only one direction. Direct Current (DC) is also produced from the battery or cell.
The electric motors produces energy through electromotive induction and is used to generate electricity in power plants. The mechanical energy is generally provided by steam turbines, gas turbines, and wind turbines. Electrical generators provide nearly all the power that is required for electric power grids.
Working of Generator
It operates on the basis of Faraday’s law of electromagnetic induction which states that an electromotive forces (EMF) is produced when a current carrying wire cuts the constant magnetic field lines, and is used to produce electricity in power plants, engines, and various applications where electrical power is required. The mechanical energy supplied to generator forces the movement of electric charges present in the wire of its windings through an external electric circuit.
This flow of electrons constitutes the output electric current supplied by the generator. This movement create an high electromotive force or voltage difference which cause the electric charges to flow, hence generating electric current. It also uses a regulator to maintain a constant output current.
Difference Between Alternator and Generator
Alternator and Generator are electrical devices used to generate electricity. They have a wide range of applications, from power generation to providing electricity in portable devices. Fundamentally both the devices are the same, but they differ in mode of operation and also have different characteristics.
In this article, we’ll discuss and understand what are Alternators and Generators, their working, and the differences based on various key characteristics.
