प्रत्यावर्ती धारा जनित्र

In this Class 12 Physics topic from Electromagnetic Induction, students learn how an AC generator converts mechanical energy into electrical energy through electromagnetic induction. The topic explains the construction and working of a rotating coil in a magnetic field, the role of slip rings and brushes, and the production of alternating emf. Students also study the associated waveform, frequency, peak value, and factors affecting the generated voltage.
