| Abstract: | According to the new course standard,aiming at the deficiency of teaching material,an improved method for making primary cell is designed.This method uses potassium dichromate as oxidant in electrolyte,shaggy cotton as salt bridge,and kryptol as anode.The improved primary cell is used in the researching experiment on the internal and output voltage of primary cell and the exploring experiment on the internal resistance of primary cell. |
