Answer 1

Answer:

Energy consume is watt*hour*quantity

Energy consume is watt*hour*quantityIn 1,2,3 case respectively

Energy consume is watt*hour*quantityIn 1,2,3 case respectively40w*5*2= 400w

Energy consume is watt*hour*quantityIn 1,2,3 case respectively40w*5*2= 400w60w*2.5*1= 150w

Energy consume is watt*hour*quantityIn 1,2,3 case respectively40w*5*2= 400w60w*2.5*1= 150w50w*10*2=1000w

Energy consume is watt*hour*quantityIn 1,2,3 case respectively40w*5*2= 400w60w*2.5*1= 150w50w*10*2=1000wTotal energy consumed 1000+150+400w=1550w

Energy consume is watt*hour*quantityIn 1,2,3 case respectively40w*5*2= 400w60w*2.5*1= 150w50w*10*2=1000wTotal energy consumed 1000+150+400w=1550wHope it helped
