Ohms law in the development of cells

Current density at low voltages in an electrical medium is governed by Ohm s Law  

The term cell, when used in a laboratory electrochemical context, refers to a system through which electrical current passes and which has two connectable electrodes 

Cells associated with electronic conductors in bedrock 

Geobatteries centred on electronically conductive, steeply-dipping mineralisation have been described for many years and most geologists are aware of their existence. However, several widely-refereneed geochemical models developed to account for SP 

Electrical conductivities of typical shallow groundwater in glacial terrain (Shoot Zone gold property, northwestern Ontario) and those of common bedrock materials converted from the usual resistivity units (from Keller and Frischknecht, 1966)
