A generator is a device that converts mechanical energy into electrical energy. It works by using a rotating coil of wire within a magnetic field, which induces an electric current. Generators are commonly used in various applications, from providing backup power during outages to supplying electricity for construction sites. There are different types of generators, including diesel generators, gasoline generators, and solar generators. Each type has its own advantages and is suited for specific needs. For example, solar generators harness energy from the sun, making them eco-friendly options for off-grid power solutions.
