AC Generator
An AC generator is an electrical device that converts mechanical energy into electrical energy. It consists of a rotating armature (rotor) and a stationary stator. When the armature is rotated by a motor, it induces an electromotive force (EMF) in the stator conductors, which is an electrical current that flows in the circuit.
The electromagnetic induction process involves the changing magnetic field created by the stator conductor generating an electromotive force (EMF) in the rotor conductor. This induced EMF opposes the original magnetic field, resulting in an electromotive force that drives current through the rotor conductor. The frequency of the induced current is determined by the speed of rotation of the armature and the magnetic field strength.
The output of an AC generator is a continuous wave of alternating current (AC) with a frequency determined by the speed of rotation of the armature. This alternating current can be used to power appliances or other devices connected to the electrical grid.
Example:
An AC generator with a speed of 120 revolutions per minute (rpm) produces an alternating current with a frequency of 60 Hz. This means that the current reverses direction twice per second
