A device consumes 1500 watts for 3 hours. How many watts does it consume?

• A. 1500 watts
• B. 4500 watts
• C. 3000 watts
• D. 2000 watts

Answer: (B)

To determine the total energy consumed by the device, you can multiply the power consumption in watts by the time it is operated in hours. In this case, the device consumes 1500 watts over a period of 3 hours. Calculating the total consumption involves the equation: Total energy consumption (in watt-hours) = Power (in watts) × Time (in hours) Substituting the given values into the equation: Total energy consumption = 1500 watts × 3 hours = 4500 watt-hours. This result indicates that the device consumes a total of 4500 watts over the 3-hour period, confirming the accuracy of the computed total. Hence, the answer reflects the total energy consumed by the device in watt-hours.
