Answer 1

hey buddy,

Here's the working of AC generator,

When the armature coil rotates in the magnetic field of strong magnets, it cuts magnetic lines of force. Thus the potential difference is set up and an induced current is set up in the coil. The direction of the induced current is according to Flemming's Right Hand Rule. In a half rotation of the coil, the current flows through the brush B1 in one direction. whenwhen mechanical force acts on the armature in clockwise direction, arm AB moves up, arm CD moves down and induced current flows in the direction of ABCD. Current flows from B2 to B1. In the other half rotation, the current flows from the brush B1 to B2 in the opposite direction. This process is repeated and the induced current is an alternating current.
