Question
In the following non planar graph number of independent loop equations are
Options
A. 8
B. 12
C. 7
D. 5

Correct Answer

5

Explanation

Number of independent loop equations are given by,

L = B - N + 1

where L : No. of loop equations

B : No. of branches = 12

N : No. of nodes = 8

L = 12 - 8 + 1 = 5.
