If a motor consumes 373 watts of power, what is its horsepower rating?

• A. 1/4 hp
• B. 1/2 hp
• C. 3/4 hp
• D. 1 hp

Answer: (B)

To determine the horsepower rating of a motor consuming 373 watts of power, you can use the conversion factor where 1 horsepower (hp) is equal to approximately 746 watts. To find the horsepower, you would divide the power in watts by the conversion factor. Performing the calculation: \[ \text{Horsepower} = \frac{373 \text{ watts}}{746 \text{ watts/hp}} \approx 0.5 \text{ hp} \] This calculation shows that a motor consuming 373 watts translates to approximately 0.5 horsepower. Therefore, the correct answer reflects that this corresponds to a 1/2 horsepower rating. This understanding of converting watts to horsepower is fundamental in electrical applications, particularly when assessing the capabilities and energy efficiency of motors.
