What is so special about silicon? Why are some materials more conductive to electricity than others? Where does static electricity come from? This 14-video lecture series introduces electronics from a materials perspective, and is based on a course which all freshman engineering students take at the National University of Singapore.

In this video:
00:31 Static electricity with balloons, wool, and glass
02:48 William Gilbert and his work on magnetism
06:40 Benjamin Franklin: positive and negative charges
08:09 Georg Matthias Bose's "Electric Kiss" friction machine
09:24 How can an insulator be electrified in static electricity?
12:19 The triboelectric series

Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos:
