Two batteries of emf 
and 
and internal resistances r 1 and r 2 respectively are connected in parallel as shown in figure.
A
The equivalent emf 
of the two cells is between 
and 
, i.e. 
of the two cells is between and , i.e. B
The equivalent emf 
is smaller than 
is smaller than C
The 
is given by 
always
is given by always D
is independent of internal resistances r 1 and r 1
Text Solution
Verified by ExpertsThe correct answer is:
A
We know that in the given circuit,
Here, 
is weighted average of 
and 
.
Naturally, its value will lie between the value of 
and 
,
i.e. 
will be less than 
and more than 
.
