Electrical generators are devices that convert mechanical energy into electrical energy, providing power for various applications. They operate on the principle of electromagnetic induction, where a conductor moving through a magnetic field generates electricity. Common types include diesel generators, gasoline generators, and solar generators. These generators are essential in both residential and industrial settings, ensuring a reliable power supply during outages or in remote locations. They come in various sizes and capacities, catering to different energy needs. Understanding how they work can help users select the right generator for their specific requirements.
