    A current of 2 A flows in a system of conductors as shown. The potential difference \[({{V}_{A}}-{{V}_{B}})\] will be                   [CPMT 1975, 76]

    A)                    \[+2\,V\]

    B)                    \[+1\,V\]

    C)                    \[-1\,V\]

    D)                    \[-2\,V\]

    Correct Answer: B

    Solution :

                 Current through each arm DAC and DBC = 1A  \[{{V}_{D}}-{{V}_{A}}=2\] and \[{{V}_{D}}-{{V}_{B}}=3\] Þ \[{{V}_{A}}-{{V}_{B}}=+1V\]
