प्रश्न
Draw a labelled diagram of an ac generator.
उत्तर
Main parts of an ac generator:
-
Armature − Rectangular coil ABCD
-
Filed Magnets − Two pole pieces of a strong electromagnet
-
Slip Rings − The ends of coil ABCD are connected to two hollow metallic rings R1 and R2.
-
Brushes − B1 and B2 are two flexible metal plates or carbon rods. They are fixed and are kept in tight contact with R1 and R2 respectively.
