Question

Electrochemical cells are arranged as depicted in the diagram above. What is the total electric potential difference of this battery if each cell has an electric potential difference of 2.0 V? 0 2.0v 0 4.0V 6.0V 12.0V none of the above

Answer 1

Note- If in figure 2 cells have different voltage then higher voltage overcome lower voltage so resultant potential difference will be equal to the higher potential.

In the branch So Resultant ab all cells are connected in series potential difference of ab brunch Vab= 2 + 2+2=6V Similarly Now Ved z 2+2+2 26v 6v So Since both both cell in figure ③ haree same voltage Resultant eledric potential difference is bv Answer is [GU]
