Atom besteht aus
Protons (+), neutrons and electrons (-) => protons and neutrons forms the nucleus around the electrons move very rapidly in certain shells
Th electrons in the outermost shell calls
valence electrons
Heat effect
electrons move in in one direction = voltage => While traveling on their way through the conductor => these oscillations produce heat
Ions?
are the carrier of electrical charge in liquid or gases
conductors
are metals (aluminum/cooper, silver, gold)
some liquids also belong to teh group of conductors => different to metals?
no electrons but ions move
Semiconductors
have a very weak conductivity => after a certain contamination a certain voltage is attained
conductivity
conductivity = the electrons in the outermost shell of the material determine its electrical conductivity
