The Energy Efficiency of Light Bulbs

One of the best topics of understanding energy efficiency is that of light bulbs. Consider the following graph, excerpted from The Science of Energy Efficiency, available from Schottenbauer Publishing.


Discussion Questions
  1. Identify the power and current required for each light bulb.
  2. Which light bulb is more efficient? Why?
  3. When the light bulbs are turned on, is the effect immediate? Why or why not?
  4. What occurs in the circuit when the light bulbs are turned on? 

Over 8,000 graphs from Schottenbauer Publishing provide additional real-life topics for student learning, including sports, transportation, construction, environment, music, entertainment/toys, and general physics.
