PPT-Current density and conductivity

LL8 Section 21 j mean charge flux density current density chargeareatime Constant current The flow in and out of every volume element is constant By continuity No charge builds up or is depleted at any point . Conductivity is one of the easiest environmental tests of aquatic samples Even though it does not tell you specific ions that are present it does quickly determine the total concentration of ions in a sample It can be used to perform a wide variety living with the lab. © 2011 LWTL faculty team. 2.

Electrochemical systems are devices or processes in which an ionic conductor mediates the inter-conversion of chemical and electrical energy. The reactions by which this inter-conversion of energy occurs involve the transfer of charge (electrons) at the interface between an electronic conductor (the electrode) and an ionic conductor (the electrolyte).
