generator, , The electrical generator works on the, , principle that, , when a straight conductor is moved, in a magnetic field,, , then current is induced in the, conductor., , Types of Generators

Generator is used to generate, , electric current., , The electric current can be - AC, current or DC current., , Thus, Electric Generators is of two, types, e AC Generator - Generates, Alternating Current (AC current), e DC Generator - Generates Direct, , Current (DC current)

AC Electric Generator consists of, , ¢ Rectangular Coil of Wire ABCD, , e A strong horseshoe magnet (or, 2 different magnets ) - If we, take 2 magnets, North Pole of, first magnet faces South Pole, of Other Magnet, as shown in, figure..., , e The coil is placed perpendicular, to the magnet as shown in, figure, , ¢ The ends of coil are connected, to two rings -R;andR2, , e The external conducting edges ,
