Essentially what is occurring is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorously. This momentum transfer model makes metal an ideal choice for a conductor; metals, characteristically, possess a delocalized sea of electrons which gives the electrons enough ...
Rectangular shaped polymer aluminium (black) and tantalum (brown) electrolytic chip capacitors Cylindrical (wound) polymer aluminium electrolytic capacitors. A polymer capacitor, or more accurately a polymer electrolytic capacitor, is an electrolytic capacitor (e-cap) with a solid conductive polymer electrolyte.
In electrolytes, electrical conduction happens not by band electrons or holes, but by full atomic species traveling, each carrying an electrical charge. The resistivity of ionic solutions (electrolytes) varies tremendously with concentration – while distilled water is almost an insulator, salt water is a reasonable electrical conductor.
The beginnings of conducting as a form of beat-keeping can be traced back to ancient times in the Egyptian, Greek, and Roman societies. Through examining historical records- notably hieroglyphics, there is evidence that points to many early societies utilizing visual and aural cuing to maintain a sense of beat, rhythm, and shape.
A piece of conducting material of a particular resistance meant for use in a circuit is called a resistor. Conductors are made of high-conductivity materials such as metals, in particular copper and aluminium. Resistors, on the other hand, are made of a wide variety of materials depending on factors such as the desired resistance, amount of ...
Electrical conductivity, a measure of a material's ability to conduct an electric current Conductivity (electrolytic), the electrical conductivity of an electrolyte in solution; Ionic conductivity (solid state), electrical conductivity due to ions moving position in a crystal lattice

Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. [1] [2] Such compounds may have metallic conductivity or can be semiconductors. The main advantage of conductive polymers is that they are easy to process, mainly by dispersion.
