Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

An understanding of electric circuits and the concepts of voltage, current and resistance enables engineers to design all sorts of useful devices and inventions that improve our lives. For example, engineers designed photovoltaic (PV) cells, commonly called solar cells, which use sunlight to make electricity. No matter what the source of the electrical power, engineers apply their understanding of how current electricity works to make devices that run the appliances and equipment that are important in our everyday lives. Understand the concept of current electricity, and the relationship between current, voltage and resistance.Recognize that electrical energy in an electric circuit can be converted to different forms of energy, such as motion, thermal and light energy. List alternative sources of electricity. Recognize that engineers apply their understanding of how electricity works to design applines and equipment that are important in our everyday lives. 50TeachEngineering.orgXochitl Zamora ThompsonSabre DurenJoe FriedrichsenDaria Kotys-SchwartzMalinda Schaefer ZarskeDenise CarlsonGuyton M.D., Arthur, C. and Hall, John E., Textbook of Medical Physiology. 10th Edition.
