The node voltage method is based on Kirchhoff's voltage law.
The branch current method uses
Answer: Option A
The expansion method for evaluating determinants is
Answer: Option D
Explanation:
For more than third order matrix, co-factor is more comfortable than expansion method to find determinants.
The first row of a certain determinant has the numbers 10 and 6. The second row has the numbers 3 and 5. The value of this determinant is
Answer: Option C
Determinant formula = |ad-bc|. 10*5-6*3=50-18=32 Answer = 32
