In this topic, you study the definition and different types of electric cells.
Cell is a device which converts chemical energy into electrical energy.
The cells are of two types:
(a) Primary cells,
(b) Secondary cells.
In both the types the electrical energy is covered from chemical energy. The primary cell is that which is able to deliver the current as soon as its components are assembled. It is the cell which cannot be recharged again. The secondary cell is the cell which have to be charged before putting into service, more over there are having completely reversible reaction and can be recharged after discharge.
