    A capacitor in connected to a cell of emf \[\varepsilon \] having some internal resistance r. The potential difference across the:

    A)  Cell is \[<\varepsilon \]         

    B)  Cell is \[\varepsilon \]

    C)  Capacitor is \[>\varepsilon \]            

    D)  Capacitor is \[<\varepsilon \]

    Correct Answer: B

    Solution :

    If capacitor is fully charged, it draw \[{{n}_{0}}\] current when no current flows in the circuit, potential difference across the cell = emf of the cell. Potential difference across the capacitor \[\left[ \therefore \,\,V=E-ir\,as\,i=0\,\therefore \,V=E \right]\]
