Question

three 2v cells are connected in series and used as battery in circuit what is the potential difference at the terminals of battery

Answer 1

HI !

Potential difference of 1 cell = 2 v

Therefore,
Potential difference of 3 cells = 3*2 = 6 v

hence,
potential difference at the terminals of battery= 6 v

Answer 2

Answer:

The potential difference at the terminals of he battery is 6 V.

 Given that the 3 cells of 2v as potential difference are in series connection.

That is,

Potential difference of each cell = 2 v

To find the potential difference of 3 cells let us find the product of 3 and 2 which will provide a potential difference of 3 cells connected in series

Potential difference of 3 cells  

= 3 x 2  

= 6
