Question

Two non-ideal batteries are connected in series. Consider the following statements
(A) The equivalent emf is larger than either of the two emfs.
(B) The equivalent internal resistance is smaller than either of the two internal resistances.
(a) A and B are correct.
(b) A is correct but B is wrong.
(c) B is correct but A is wrong.
(d) A and B are wrong.

Answer 1

Answer:

(b) A is correct but B is wrong

Answer 2

Answer:

(b) A is correct but B is wrong.

Explanation:

Since, the batteries are connected in series so the whole circuit is in series and the equivalent resistance in series is always equal to the sum of the the number of resistances. So, resistance will not change. But A is correct because electomagnetic field will change as it depends upon the distance also.
