## With respect to branch-path incidence matrix if the pth branch is in the path from qth bus to reference and oriented in the same direction then

With respect to branch-path incidence matrix if the pth branch is in the path from qth bus to reference and oriented in the same direction then:

1. Kpq = -1
2. Kpq = 1
3. Kpq = 0

Correct answer: 2. Kpq = 1

## In element node incidence if pth element is not incident to qth node then which of following is correct
