    Potential difference between A and B in the circuit shown here is

    A) 4 V                              

    B) 5.6 V   

    C) 2.8 V                           

    D) 6 V

    Correct Answer: B

    Solution :

    (b) 5.6 V Apply KVL in the given circuit,             \[6-8l-4-2l=0\] Or         \[2-10l=0\] Or         \[l=\frac{2}{10}=0.2\,A\] \[{{V}_{AB}}=4+l\times 8=4+0.2\times 8=5.6\,V\]
