Answer:
3.78 kWh
Explanation:
Power of incandescent bulb = 60 W = 0.06 kW
Power of fluorescent bulb = 15 W = 0.015 kW
Number of hours in a week if each day the light is turned on 12 hours
12×7 = 84 hours
Difference in power
0.06-0.015 = 0.045 kW
Multiplying with the number of hours
[tex]0.045\times 84=3.78\ kWh[/tex]
Hence, the fluorescent bulb will consume 3.78 kWh less electricity energy than the incandescent bulb.
