Question

In a house two 60 W electric bulbs are lighted for 4 hours, and three 100 W bulbs for 5 hours every day. Calculate the electric energy consumed in 30 days.

Answer 1

Answer:

Energy consumed in kWh for 30 days will be 52.2 W

Explanation:

total power = 60x4 + 300x5 = 1740 Watt

Energy consumed in kWh for 1 day = 1740/1000

Energy consumed in kWh for 30 days =  1.73x30

Energy consumed in kWh for 30 days =  52.2 W
