Polarisation: When a primary cell delivers current to an external circuit, chemical reactions occur inside the cell, and the products of the reaction accumulate around the internal electrodes (anode and cathode) of the cell.
Local Action. This is the tendency for the chemically active components of a cell to react with each other, and so become exhausted even when no current is being drawn from the cell.The zinc becomes coated with hydrogen bubbles, as a result of its reacting with the acid, even when no current is being drawn. After a while either the zinc will be entirely consumed, or the acid will be neutralised, all to no useful effect.
you can see local action actually happening. The zinc becomes coated with hydrogen bubbles, as a result of its reacting with the acid, even when no current is being drawn. After a while either the zinc will be entirely consumed, or the acid will be neutralised, all to no useful effect.
