View Edit History Print PDF ## Metallic conductor How can a lot of loose electrons cause a metal to be a good conductor? This is because each electron is an electric charge that is free to move. Moving electric charges can make up a current. But this is only true if they move the same way. Due to thermal kinetic energy of the electrons and ions in the metal, these conduction electrons move in a random, disordered way, with a velocity close to 106 m/s. In total, however, they have zero net velocity because their motion is not ordered. However, if an external field is applied, then the net motion of the electrons will follow the field.

Download the self-executable JAR file or a ZIP file with the XML source code for this example. To inspect and run the example, you will need to have EJS installed in your computer (see Installation), uncompress the downloaded ZIP file anywhere in the source directory of your EJS workspace and load it with EJS.
