Question

explain the working principle of electric generator

Answer 1

An electric generator consists of a rotating rectangular coil ABCD placed between the two poles of a permanent magnet.

When the axle attached to the two rings is rotated such that the arm AB moves up in magnetic field produces by the permanent magnet.the coil is rotated clockwise.By applying Flemings right hand rule,induced currents are set up in these arms are along with the direction AB And CD.
If there are larger numbers of turns in the coil,the current generated in each turn adds up to give a large current through the coil.

Answer 2

The working of electric generator is based on electromagnetic induction. There are two poles inside the electric generators. With the help of electromagnetic induction, The generator converts the mechanical energy to the electric energy.

The two ends of electric generator are connected with two different semi-circular rings. There is also a brush inside the electric generators to which, this circular rings are connected with.

Working:

When the loop is rotated, in the magnetic field, then it's one side moves upward and one side moves to the downward direction.   Due to which, the magnetic flux that is connected with the two loops changes and current is inducted and hence  this is how, the current is  produced in the  electric generator.  

Components of Generator:

• Alternator
• Fuel system
• Engine
• Control Panel
• Lubrication system
• Battery Charger
• Voltage regulator
