How is power mesured?

Power is measured as the rate at which energy is transferred or converted. In electrical systems, it is typically measured in watts (W), where one watt equals one joule per second. For mechanical power, the measurement may involve horsepower or foot-pounds per minute, depending on the context. In general, the formula for power can be expressed as P = E/t, where P is power, E is energy, and t is time.
