=== In ionic liquids/electrolytes===

In [[electrolyte]]s, [[electrical conduction]] happens not by band electrons or holes, but by full atomic species ([[ion]]s) traveling, each carrying an electrical charge. The resistivity of ionic liquids varies tremendously by the salt concentration - while distilled water is almost an insulator, salt water is a very efficient electrical conductor. In [[cell membrane|biological membranes]], currents are carried by ionic salts. Small holes in the membranes, called [[ion channel]]s, are selective to specific ions and determine the membrane resistance. Innit Bruv.
