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 copper 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 diesel generators, gasoline generators, and wind turbines. Each type has its own method of generating electricity, but they all serve the same purpose: to provide power for homes, businesses, and industries. Generators can be portable or stationary, depending on their intended use.
