These factors serve to increase the resis4vity of metals with increasing temperature (contrasted to the behavior of semiconductors). Electrical Resis4vity 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. Resistors are two- terminal...
