Power output

Power output is a measure of how quickly work is done or energy is transferred over time. It indicates the rate at which a device or system delivers energy, such as a car engine producing a certain amount of horsepower or an electrical appliance consuming a specific wattage. Think of it as the speed at which something can perform its tasks; higher power output means more work can be done in less time. It combines both the amount of energy involved and the time it takes, making it a key concept in understanding the efficiency and capability of machines and systems.
