Electric Power

Electric power is the rate at which electrical energy is transferred or used in a system, measured in watts (W). It represents how quickly electrical energy is being converted into other forms of energy, like light, heat, or motion. For example, a 100-watt light bulb uses power at a rate of 100 joules per second. Electric power is essential for powering homes, businesses, and devices, and is generated from sources like fossil fuels, nuclear, or renewable energy. Understanding power helps manage energy consumption efficiently and ensures devices operate safely and effectively.
