Find the cost of running a 60W lamp for 24 hours. If 1kW hr cost 5 naira
Answer Details
To find the cost of running a 60W lamp for 24 hours, we need to calculate the energy consumed by the lamp in kilowatt-hours (kWh) and then multiply by the cost of one kWh.
First, let's convert the power of the lamp from watts to kilowatts by dividing it by 1000:
60 W ÷ 1000 = 0.06 kW
Next, we can calculate the energy consumed by the lamp in kWh by multiplying the power by the time:
0.06 kW × 24 h = 1.44 kWh
Finally, we can find the cost of running the lamp by multiplying the energy consumed by the cost per kWh:
1.44 kWh × 5 naira/kWh = 7.2 naira
Therefore, the answer is option (C) 7.2 naira.
