This edition: Alternating Current
“The Mechanical Universe..and Beyond” helps teachers demystify physics by showing students what looks like. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance. Visits with Newton, Leibniz, Maxwell, and others trace the evolution of theories and challenge students to observe physical processes going on around them.
In this episode: Electromagnetic induction makes it easy to generate alternating current while transformers make it practical to distribute it over long distances.
