    In the circuit, the potential difference across\[PQ\] will be nearest to

    A) \[9.6\,\,V\]                        

    B) \[6.6\,\,V\]

    C) \[4.8\,\,V\]                        

    D) \[3.2\,\,V\]

    Correct Answer: D

    Solution :

    Potential difference across \[PQ\] ie, potential difference across the resistance of \[20\Omega \] is                                                                        \[V=i\times 20\] and\[i=\frac{48}{(100+100+80+20)}=0.16A\] \[V=0.16\times 20=3.2volt\]
