    If a conductor of \[4\,\,\Omega \] is connected in series with another conductor of \[8\,\,\Omega \] and a potential difference of 6 V is applied across the combination, the total resistance of the circuit is X, the current passing through the circuit is Y and potential difference across the conductor of \[8\,\,\Omega \] is Z, find the value of X, Y and Z.

    A) \[X-12\,\,\Omega ,\,\,Y-0.5\,A,\,\,Z-4\,\,V\]

    B) \[X-12\,\,\Omega ,\,\,Y-1\,A,\,\,Z-4\,\,V\]

    C) \[X-12\,\,\Omega ,\,\,Y-0.5\,A,\,\,Z-6\,\,V\]

    D)  \[X-2.6\,\,\Omega ,\,\,Y-0.5\,A,\,\,Z-4\,\,V\]

    E)  None of these
