Electrical Conductivity of Fluids

Electric current will readily flow through certain solids and liquids when a voltage difference exists between two points. In solid materials it consists of electron movement through the atomic structure, it’s referred to as electronic current flow. Current carriers are of a fixed charge an almost negligible mass, any limitations on flow rate are determined by the characteristics of the conducting medium more than the carrie

Polarization

Ions traveling toward the electrodes will quickly form dense clouds near the electrode surfaces. They cannot physically cross the solid/liquid barrier, and the voltage is usually too low for significant electrolysis to occur (forming elemental sodium and chlorine gas for our example.) But the cloud of negative ions will present a rising counter emf at the positive electrode, and vice-versa. The result is that current flow rapi
