For an oriented graph, each column of the node-branch incidence matrix corresponding to an ordinary branch contains?

  • AOne +1 and one -1
  • BTwo +1 entries only
  • COne nonzero entry only
  • DAll zero entries
Report an error
Correct Answer: A. One +1 and one -1
Explanation: An oriented branch leaves one node and enters another, so its incidence-matrix column has one +1 and one -1 under a consistent sign convention.
