Two cells of emf 
and 
are joined in opposition (such that 
). If 
and 
be the internal resistance and 
be the external resistance, then the terminal potential difference is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As emfs 
and 
are in opposition and 
, so equivalent emf is
The equivalent resistance of the circuit is
The current in the circuit is
The terminal potential difference is
