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:
00:20 Conductivity of table salt (NaCl)
01:05 The surface of a material is different than the interior.
02:38 Strength of ionic bonds in table sale (NaCl)
07:11 Conductivity of molten salt (NaCl)
09:17 Electrolysis of water with dissolved salt (NaCl)
Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos:
