  • question_answer
    A capacitor is connected to a cell of emf E having some internal resistance r. The potential difference across the:

    A)  cell is < E                            

    B)         cell is E

    C)         capacitor is > E                 

    D)         capacitor is < E

    Correct Answer: B

    Solution :

    When capacitor is fully charged, it draws no current. When no current flows in the circuit, potential difference across the cell = emf of the cell       = potential difference across the capacitor.
