Question

in a house 2 bulbs of 50 w each are used for 5 hours a day and two 70 w each fans are used 10 hours a day . calculate the units of electricity consumed in a month of 30 days

Answer 1

Bulbs= 500W
Fans= 1400W
A day= 1900W
A month= 57000W

Answer 2

Hey there! ☺☻☺

1 bulb power = 50 W
1 fan power = 70 W

Energy consumed by bulb in one day = 50*2*5 = 500 W h
Energy consumed by fans in one day = 70*2*10 = 1400 W h
Total Energy consumed in one day = 1400 + 500 W h
                                                        = 1900 W h
Total Energy consumed in 1 month = 1900 * 30 = 57000 W h
                                                         = 57000/1000 kWh
                                                         = 57 kWh

Hope It Helps You! ☺☻☺
