How many watts are equivalent to 1 horsepower in a motor?

• A. 500 Watts
• B. 746 Watts
• C. 1000 Watts
• D. 1200 Watts

Answer: (B)

One horsepower is equivalent to 746 watts. This conversion stems from the historical definition of horsepower, which was created by James Watt to describe the power output of steam engines. In the context of electric motors, knowing that 1 horsepower equals 746 watts is essential for determining the electrical power needed to achieve the desired mechanical output. Understanding this relationship facilitates accurate calculations in various engineering and technical applications, especially when converting between different units of power.
