Test Yourself! (Electrical Properties of Materials #14)

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: 00:10 Problem 1: How is potential energy lost? 01:34 Problem 2: Calculation of kinetic energy of an electron 02:42 Problem 3: Path of electron when calculating energy 03:36 Problem 4: Path of electron during ionization 04:34 Problem 5: Static electricity (teflon/silk) 06:00 Problem 6: Why is NaCl an insulator? 07:03 Problem 7: Bound electrons versus free electrons 08:01 Problem 8: Time of a bolt of lightning 09:04 Problem 9: Selection of appropriate electron source 10:12 Problem 10: Calculation of resistivity given doping level 11:52 Problem 11: Adjusting of doping level if already doped Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos: https://www.edx.org/course/electronic...
