Electric Circuits
Electricity and magnetism play a profound role in almost all aspects of life. From the moment you wake up, to the moment you go to sleep (and even while you’re sleeping), applications of electricity and magnetism provide tools, light, warmth, transportation, communication, and even entertainment. Despite its widespread use, however, there is much about these phenomena that is not well understood.
