A battery of emf 2 volt and internal resistance \[0.1\]ohm is being charged with a current of 5 ampere. The potential difference between the two terminals of the batteries is
A) \[2V\]
B) \[0.5\,V\]
C) \[1.5\,V\]
D) \[2.5\,V\]
Correct Answer:
D
Solution :
For charging, \[V=E+Ir\]or,\[V=2+0.1\times 5=2.5\]
