Electric power is the rate at which electrical energy is transferred by an electric circuit. It is measured in watts (W) and can be generated from various sources, including fossil fuels, nuclear energy, and renewable resources like solar and wind. Electric power is essential for operating homes, businesses, and industries, powering everything from lights to appliances. The flow of electric power is facilitated by the movement of electrons through conductors, such as copper wires. This flow can be direct current (DC), where electrons move in one direction, or alternating current (AC), where the direction of flow changes periodically. Understanding electric power is crucial for efficient energy use and management.
