  • question_answer
    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) 1.5 V                                     

    D) 8.5 V

    Correct Answer: D

    Solution :

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