Question
Which of the following statements is not true?a.Electrical Appliances have become more energy efficientb.A LED light lasts up to 5 times longerc.A modern LED light is 60 percent more efficient than traditional incandescent lightsd.Incandescent lamps are the most efficient
Solution 1
The statement that is not true is: "d. Incandescent lamps are the most efficient". Incandescent lamps are actually less efficient than modern LED lights.
Solution 2
The statement that is not true is: "d. Incandescent lamps are the most efficient". Incandescent lamps are actually less efficient than modern LED lights. Most of the energy they use is converted into heat rather than light.
