Define Electric Generator_____

Answer 1

ᴇʟᴇᴄᴛʀɪᴄ ɢᴇɴᴇʀᴀᴛᴏʀ –

The electric generator is a machine for producing electric current electricity.
The electric generator converts mechanical energy into electrical energy.
A small generator called a dynamo.
For example, the small generator used on bicycles for lighting purpose is called a bicycle dynamo.

ᴘʀɪɴᴄɪᴘʟᴇ ᴏғ ᴇʟᴇᴄᴛʀɪᴄ ɢᴇɴᴇʀᴀᴛᴏʀ –

The electric generator is an application of electromagnetic induction. The electric generator works on the principle that when a straight conductor is moved in a magnetic field, then current is induced in the conductor. In an electric generator, regulator coil is made to rotate rapidly in the magnetic field between the poles of the horseshoe - type magnet. When the coil rotates, it cuts the magnetic field lines due to which AC current is produced in the coil.

ᴇʟᴇᴄᴛʀɪᴄ ɢᴇɴᴇʀᴀᴛᴏʀs ᴀʀᴇ ᴏғ ᴛᴡᴏ ᴛʏᴘᴇs –

1). Alternating current generator (AC generator), and
2). direct current generator ( DC generator).

ᴀᴄ ɢᴇɴᴇʀᴀᴛᴏʀ–

“AC generator” means “alternating current generator”. That is an AC generator produced alternating current, which river is direction continuously.

ᴅᴄ ɢᴇɴᴇʀᴀᴛᴏʀ–

DC generator is used in order to obtain direct current. if we replace the slip rings of an AC generator by a commutator then it become a DC generator.

Answer 2

Electric generator is a device that convert mechanical energy into electrical energy for the use of an external circuit.

The first electro magnetic generator,the Faraday disk was invented in 1831 by father of electricity Michael Faraday.

A dynamo generate direct current through the use of a commutator.

Alternator generate alternating current .
