An electric generator is a device that converts mechanical energy into electrical energy. It works on the principle of electromagnetic induction, where a conductor, such as a wire, moves through a magnetic field to produce electricity. Generators are commonly used in power plants, backup systems, and various applications where electricity is needed. There are different types of electric generators, including alternating current (AC) generators and direct current (DC) generators. AC generators are widely used for power distribution, while DC generators are often used in smaller applications, such as battery charging. Both types play a crucial role in providing electricity for homes and industries.
