Q4 of 6 Page 27

Electric cells having 2V potential difference each have been connected in the form of a battery. What will be the total potential difference of the battery in both cases?


Since the cells are in the same direction the potential difference in the battery will be added up.


Total potential difference = 2V+ 2V +2V = 6 volt



Since the cells are in the same direction the potential difference in the battery will be added up.


Total potential difference= 2V+2V+2V+2V =8 volt.
