Question

A 250 watt electric bulb is lighted for 5 hours daily and for 6 watt bulb are lighted for 4.5 hours daily calculate the energy consumed (in kwh) in the month of february

Answer 1

Time of working of 250W bulb=5hours
Time of working of 6W bulb=4.5hours
Energy consumed by 250W bulb /day=250W x 5hours
=1250Wh
Energy consumed by 6W bulb/day=6W x 4.5hours
=27Wh
Total energy consume per day= 1250Wh + 27Wh
=1267Wh
Energy consumed for the month of February=1267Wh x 28days
=35476Wh
