A power supply system is a network that provides electrical energy to various devices and systems. It converts different forms of energy, such as solar, wind, or fossil fuels, into usable electricity. This system includes components like transformers, generators, and distribution lines that work together to ensure a stable and reliable power supply. These systems are essential for homes, businesses, and industries, as they support everyday activities and operations. Power supply systems can be centralized, like those found in power plants, or decentralized, such as solar panels on rooftops. Efficient management of these systems is crucial for sustainability and energy conservation.
