Question
Two nonideal batteries are connected in parallel. Consider the following statements
(I) The equivalent emf is smaller than either of the two emfs.
(II) The equivalent internal resistance is smaller than either of the two internal resistance.
(I) The equivalent emf is smaller than either of the two emfs.
(II) The equivalent internal resistance is smaller than either of the two internal resistance.
Options
A.Both I and II are correct
B.I is correct but II is wrong
C.II is correct but I is wrong
D.Each of I and II is wrong.
Solution
Eeq =
req = 
Therefore statement II is correct bul I is wrong.
Therefore statement II is correct bul I is wrong.
