Electrical Engineering XYZ MCQs

In a 4*4 Y bus matrix the number of non-zero elements are 12. The sparsity of system is:

1. 1
2. 0.25
3. 0.5
4. 0.75

Correct answer: 2. 0.25

Solution:

Total number of elements in 4×4 bus matrix = 16

Number of non-zero elements = 12

Number of zero elements = 4

Sparsity = Number of zero elements/Total number of elements = 4/16 = 0.25
