ac generator and dc generator

What is an AC generator (alternator), and how does it work?

An AC generator, also known as an alternator, is a device that converts mechanical energy into alternating current (AC) electrical energy. It is commonly used in power generation systems to produce electricity. The primary function of an AC generator is to generate a changing electrical current that periodically reverses direction, creating a ...
