Unformatted text preview: 17 Polyethylene 10 - 10 - 6 GaAs 10 Selected values from Tables 18.1, 18.3, and 18.4, Callister & Rethwisch 8e. Electrical Resistivity As temperature increases, the magnitude of thermal vibra4ons increases as does the number of vacancies. These factors serve to increase the resis%vity of metals with increasing temperature. Capacitors and Resistors Capacitors consist of a dielectric* sandwiched between two conductors. A charge builds when a voltage is applied. Eventually the charge is released in one burst. *An electrical insulator that can be polarized. Resistors are two- terminal components that add electrical resistance to a circuit. Band Structure: electron orbital energy in solids energy levels are maintained as if the atom was isolated e- are perturbed by electrons and nuclei of adjacent atoms. In a solid, energy states split into a series of closely spac...
