Question

In a house 4 bulbs of 60 watt each are lighter for 5 hours daily.calculate the energy consumed in aonth of 30days

Answer 1

energy= power*time

energy=60*5

this is the energy consumed for 1 day by 1 bulb =300 J

energy consumed for 1 day by 4 bulb =300*4=1200 J

energy consumed for 30 day by 4 bulb = 1200*30 = 36000 J
