    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,\[V=2+0.1\times 5=2.5\]
