Question= What is Primary cells ? 

Answer= These are the cells which provide current as a result of irreversible chemical reaction. These cells are discarded after use when the entire chemical energy in them has converted into electrical energy. Thus these cells are 'use and throw ' type of cells and cannot be recharged. Depending upon the material of electrodes, we have different of primary cells e.g. simple voltaic cell, Leclanche cell, Daniel cell, dry cell, etc.
