Umweltpolitik und Umweltökonomielly charged by gaining or losing electrons, one example being when certain materials are rubbed (glass with silk or ebonite with fur). It is also possible to charge materials using in the first instance moving electric charge, that is electric current, the charge then remaining on the materials.

Electrical resistance, amounts of energy per electron, Nichrome needing about ten times as much as iron. The same voltage (which is a measure of energy per unit charge and therefore energy per electron) will thus cause more current in the copper than in the iron, even less in Nichrome and least of all in glass. Copper an
