  • question_answer
    A 5.0 amp current is setup in an external circuit by a 6.0 volt storage battery for 6.0 minutes. The chemical energy of the battery is reduced by                                            [KCET 2005]

    A)            1.08 ´ 104 J                            

    B)            1.08 ´ 10-4 volt

    C)            1.8 ´ 104 J                              

    D)            1.8 ´ 104 volt

    Correct Answer: A

    Solution :

                       The chemical energy reduced in battery \[=VIt=6\times 5\times 6\times 60\,J\]\[=10800\,J=1.08\times {{10}^{4}}J\]
