QUESTION: 11

Which of the following is correct?

  1. Cut set is the number of branches that are to be removed to break the graph into two parts.

  2. Rank of cut set matrix = Rank of incidence matrix

Adding one twig to the existing co-tree results in one tie-set.
Solution:

Cut set is minimum number of branches to be removed to break graph into two parts.
Adding a link to existing tree results in one positive set

QUESTION: 12

Find the voltage Vx in the given[/expand] circuit.
Solution:

 From the circuit applying Kirchhoff’s voltage law, we can write 50= 15+ 10+ 15+Vx => Vx= 10V.
