Generators are devices that convert mechanical energy into electrical energy, providing a reliable power supply in situations where grid electricity is unavailable or insufficient. They work by driving a rotor inside a magnetic field, producing alternating current (AC) or direct current (DC) electricity depending on the design.
Available in various types—including diesel, gasoline, natural gas, solar, and hybrid generators—they are used in homes, businesses, construction sites, hospitals, and industrial facilities to ensure uninterrupted power. Generators come in a wide range of sizes, from small portable units for emergency backup to large industrial models capable of powering entire facilities.
