Now, to determine the cost of the energy consumed, we multiply the energy consumption by the cost per kilowatt-hour:
Cost = Energy Consumption × Cost per kWh
= 2.1 kWh × Php9.62/kWh
= Php20.202
Therefore, it would cost Php20.202 to operate a 20" desk fan for 12 hours, assuming it has a power rating of 175 watts and the cost of electrical energy is Php9.62/kWh.
To calculate the cost of operating the 20" desk fan for 12 hours, we need to find the energy consumption in kWh first. The power consumption of the fan is given as 175 W. To convert this to kW, we divide by 1000:
175 W ÷ 1000 = 0.175 kW
Now, we can calculate the energy consumption in kWh by multiplying the power consumption by the operating time:
0.175 kW × 12 hours = 2.1 kWh
Finally, we can calculate the cost of operating the fan by multiplying the energy consumption by the cost per kWh:
2.1 kWh × Php9.62/kWh = Php20.20
Therefore, it would cost Php20.20 to operate the 20" desk fan for 12 hours.
Answers & Comments
Answer:
PHP=20.202
Explanation:
To calculate the cost of operating a 20" desk fan for 12 hours, we need to know the power rating of the fan in watts.
Assuming the power rating of the fan is 175 watts, we can calculate the energy consumption in kilowatt-hours (kWh) using the formula:
Energy Consumption (kWh) = (Power rating × Hours used) / 1000
= (175 watts × 12 hours) / 1000
= 2.1 kWh
Now, to determine the cost of the energy consumed, we multiply the energy consumption by the cost per kilowatt-hour:
Cost = Energy Consumption × Cost per kWh
= 2.1 kWh × Php9.62/kWh
= Php20.202
Therefore, it would cost Php20.202 to operate a 20" desk fan for 12 hours, assuming it has a power rating of 175 watts and the cost of electrical energy is Php9.62/kWh.
