Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor...
Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a...
Light a light bulb by waving a magnet. This simulation of a Faraday's Law is from the Physics Education Technology website of University of Colorado. It is accessible for teachers and students alike. Included are links...
A Summary of Students' Mental Models and Their Applications in Contexts Pertaining to Newton's II Law
In this study, presented at the 2002 Physics Education Research Conference, authors describe their investigation of students' use of Newton's II law in mechanics and electricity and magnetism contexts. They interviewed...
These lecture notes cover the effects of science and technology on society and how our understanding of the basic structure and operating principles of the universe has affected human lives. Examples of beneficial...
