    We can add maximum number of six branches to make to resulting structure becomes nonplanar as shown in the figure.


    Correct Option: B

    We can add maximum number of six branches to make to resulting structure becomes nonplanar as shown in the figure.

    We know that
    b = n – 1 (where b = no. of tree branches)
    3 = n – 1
    or n = 4
    Now, number of equation (i.e. meshes) required is given by the relation.
    No. of equation = b – n + 1 = 6 – 4 + 1 (where b = no. of branches) = 3

    Correct Option: B

    We know that
    b = n – 1 (where b = no. of tree branches)
    3 = n – 1
    or n = 4
    Now, number of equation (i.e. meshes) required is given by the relation.
    No. of equation = b – n + 1 = 6 – 4 + 1 (where b = no. of branches) = 3


  1. A planar graph has 4 nodes and 5 branches the number of meshes in dual graph is—

    We know that
    b = n – 1 + L; where b = no. of branches
    5 = 4 – 1 + L n = no. of nodes
    or L = 2 L = no. of loops
    since node pairs and meshes are interchanged in dual so in dual the number of meshes is 3.

    Correct Option: C

    We know that
    b = n – 1 + L; where b = no. of branches
    5 = 4 – 1 + L n = no. of nodes
    or L = 2 L = no. of loops
    since node pairs and meshes are interchanged in dual so in dual the number of meshes is 3.
