    In the circuit shown, the point ?B? is earthed. The potential at the point ?A? is

    A)                    14 V

    B)                    24 V

    C)                    26 V

    D)                    50 V

    Correct Answer: B

    Solution :

                 Current in the given circuit \[i=\frac{50}{(5+7+10+3)}=2A\] Potential difference between A and B \[{{V}_{A}}-{{V}_{B}}=2\times 12\] Þ \[{{V}_{A}}-0=24V\] Þ \[{{V}_{A}}=24\,V\]
