Electrical supply refers to the provision of electrical energy to homes, businesses, and industries. It involves the generation, transmission, and distribution of electricity from power plants to end-users. The electricity is typically generated from various sources, including fossil fuels, nuclear energy, and renewable resources like solar and wind. The electrical supply system consists of several components, including power lines, transformers, and substations. These elements work together to ensure that electricity is delivered safely and efficiently. Consumers receive electrical supply through utility companies, which manage the infrastructure and billing for the electricity used.
