Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Convert horsepower to watts

P = 5 \times 746 \frac{\mathrm{watts}}{\mathrm{horsepower}}
- First, recall the conversion factor: 1 horsepower = 746 watts - Given: Motor is 5 horsepower

Step 3:
: Calculate total electrical power

P = 5 \times 746 = 3,730 \mathrm{~watts}
- Multiply the number of horsepower by the conversion factor

Final Answer

Key Insights: - The conversion from horsepower to watts is direct and linear - 1 horsepower consistently equals 746 watts - This calculation assumes 100% efficiency (which is ideal; real-world motors have some energy loss)
