Q13 of 126 Page 196

Two non-ideal batteries are connected in parallel. Consider the following statements:

(A) The equivalent emf is smaller than either of the two emfs.


(B) The equivalent internal resistance is smaller than either of the two internal resistances.


Let and be the emf of battery 1 and battery 2 respectively. And and be the internal resistance of battery 1 and battery 2 respectively.


The two batteries are connected in parallel.


Equivalent emf



The equivalent internal resistance



if two batteries are connected in parallel then the equivalent emf is larger than either of the two emfs and the equivalent internal resistance is smaller than either of the two internal resistances. Statement B is correct ad A is wrong. So option C is correct.
