Using engaging animation sequences to demonstrate core concepts, this program looks at the origins and development of our knowledge of direct current electricity. The video begins with the first uses of static electricity by the Greeks, then guides viewers through discoveries made by William Gilbert, Luigi Galvani, Alessandro Volta, and others during subsequent centuries. Students will gain an understanding of the chemical battery, the "complete"...

This Science Screen Report examines the production, transportation, and consumption of electricity. Using the Hoover Dam as an example of efficient hydroelectric power generation, the program illustrates how transformers raise or lower voltage to manageable levels and how electricity is specifically channeled to illuminate buildings, power devices, and propel vehicles. Vital electrical concepts are discussed, including the difference between alternating...
