Electrical Engineering MCQ

Normally, the Z bus matrix is a:

1. Sparse matrix
2. Null matrix
3. Unity matrix
4. Very dense

Correct answer: 4. Very dense

Explanation: The Z bus matrix can be computed by matrix inversion of the Y bus matrix. Since the Ybus matrix is usually sparse, the explicit Z bus matrix would be dense and very memory intensive to handle directly.
