The basics of current, voltage, power, time, and energy are reviewed. This is the background knowledge needed to understand the energy consumption measurements described subsequently. By extrapolating, you can see that even “small” continuous loads can mount up to appreciable energy consumption over the year.

Information and ideas:
• Observe the safety information in the related “Tracking down ’energy hogs’ (teacher information)” teaching methods, which are available on the media portal of the Siemens Stiftung, as well as the applicable safety guidelines for your school and discuss them with your students.
• A digital electric power consumption meter is needed to conduct the experiment.
• The answers to the questions contained in the experimentation instructions are found in the anwer sheet of the same name.
