D
is independent of internal resistances 
and 
Text Solution
Verified by ExpertsThe correct answer is:
A
The equivalent emf 
of the two cells is between 
and 
,
The cells of emf 
and 
with internal resistance 
and 
respectively.
In parallel combination, the relation between equivalent emf and equivalent resistance is,
The resistance in parallel combination is,
From the above equation,
In question,
Then The equivalent emf 
of two cell is between 
and 
.
