answered-by-expert Expert Answer
Electrical cells are the source of direct current. For example we use the dry cell to use in torch lights, clocks and remote controls etc. 
In a cell chemical energy changes into electrical energy when current drawn from the cell using devices like torch lights and clocks.
 
There are two kinds of cells. They are primary and secondary cells. Primary cells are use and throw type. Primary cells provide cureent as a result of irreversible chemical reaction. primary cells can not be recharged.
 
In secondary cells, chemical reactions are reversible and can be recharged
