The ceiling fixture in lucinda's room uses four 50 watt bulbs.The chandelier above her dining room table uses six 100 watt bulbs.how much more electrical energy does the chandelier use than the ceiling fixture Explain?
The ceiling fixture uses (4 x 50)= 200 watts when it's on. The chandelier uses (6 x 100) = 600 watts when it's on. When they're both on, the chandelier uses (600 - 200) = 400 more joules of energy than the ceiling fixture uses, every second.
