Jordan wants to know the difference between using a 60-W and 100-W lightbulb in her lamp. She calculates the energy it would take to use each bulb for 30 s by using this equation:

Power = Energy transferred (J)/time (s)

What is the difference in the amount of energy transferred by the two bulbs during this time?
