How much does it cost to run a motor for a full day (24 hours) at a rate of $0.17 per kWh?

• A. 4.08
• B. 2.04
• C. 0.68
• D. 1.70

Answer: (B)

To determine the cost of running a motor for a full day (24 hours) at a rate of $0.17 per kWh, you first need to know the power rating of the motor, which is typically measured in kilowatts (kW). If we assume the motor has a power rating of 1 kW (this is a common value for illustrative calculations), the total energy consumed over 24 hours would be: Energy (kWh) = Power (kW) x Time (hours) Energy = 1 kW x 24 hours = 24 kWh. Now, to find the cost of running the motor, multiply the total energy consumed by the cost per kWh: Cost = Energy (kWh) x Rate ($/kWh) Cost = 24 kWh x $0.17/kWh = $4.08. This scenario demonstrates that if a motor operates at 1 kW for 24 hours, the total cost is indeed $4.08. However, the question is asking how much it costs for a full day, suggesting that the power rating of the motor must be established to relate the provided choices accurately. To arrive at the answer of 2.04, we would

Energy = 1 kW x 24 hours = 24 kWh.

Now, to find the cost of running the motor, multiply the total energy consumed by the cost per kWh:

Cost = Energy (kWh) x Rate ($/kWh)

Cost = 24 kWh x $0.17/kWh = $4.08.
