What is the difference between primary cell and secondary cell |
|
Answer» Primary cell cannot be recharged whereas a secondary cell can be recharged.In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible.The internal resistance is high for a primary cell whereas it is LOW for a secondary cell.In a primary cell, chemical ENERGY is converted into electrical energy when CURRENT is DRAWN from it whereas in a secondary cell electrical energy is converted into chemical energy when current is passed through it and chemical energy is converted into electrical energy when current is drawn from it. A primary cell is light and less expensive whereas a secondary cell is heavy and expensive. |
