Description: Illustrates variation of conductivity with temperature through a simple experiment in which a current is sent through a metal and a semiconductor while heat is applied to each. Shows an animated sequence of moving electrons responding to a perpendicularly oriented magnetic field to explain the difference. Demonstrates a method for measuring Hall voltage and records this measurement taken for an N-type semiconductor, a P-type semiconductor, and a metal., Illustrates variation of conductivity with temperature through a simple experiment in which a current is sent through a metal and a semiconductor while heat is applied to each.
