AC Generator

The video explains how electromagnetic induction is used in AC generators. It describes the structure of an AC generator, which includes a coil that rotates within a magnetic field. The video details the working principle, showing how the coil's movement induces an electromotive force (emf) and generates alternating current. It also explains the direction of current flow and how it changes with the coil's rotation, completing a cycle every 360 degrees.
