    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 \[i=\frac{48}{(100+100+80+20)}=0.16\,A\] \[\therefore \]  \[V=0.16\times 20=3.2\,volt\]
