        A battery of emf 10 V and internal resistance\[3\,\Omega \]is connected to a resistor. The current in the circuit is 0.5 A, The terminal voltage of the battery when the circuit is closed is

    A)  10 V                                     

    B)  0 V

    C)  1.5V                                     

    D)  8.5V

    Correct Answer: D

    Solution :

                     Terminal voltage of the battery after closing the circuit is \[V=E-ir\] \[=10-0.5\times 3\] \[=10-1.5\]  \[=8.5V\]
