Application of KVL and KCL and Matrix 4 x 4

SOLVE FOR THE CURRENT VALUE OF X , Y, Z. You may wish to verify in your electronic lab kit the actual current flowing in each loop.

Application of four simultaneous linear equations

X = A

Y = A

Z = A

INITIAL CONDITION:

Answer, X = 1 A detX =

Answer, Y = 2 A detY =

Answer, Z = 1 A detZ =

Answer, W = detW =

determinant 4 x 4 =

Validate your answer by substituting the value of X, Y, and Z in original equations.

You need to complete all the input box then NaN (Not a Number) error message will be fixed. Automatic computation

Reviewer on how to compute for determinant value of 4 x 4 Matrix.

Acquiring knowledge and skill on how to solve for determinant of 4 x 4 matrix is important in solving any four simultaneous linear equation. In the above example, determinant X ( detX), detY, detZ, and detW were computed. Then following Cramer's Rule, the solution for value of X, Y , Z, and W can be calculated. Doing this calculation by hand is very time consuming but thanks to computer and internet advancement, it is now possible to solve this problem in less than a minute using your smartphone. Now our brain can be used for higher level of thinking such as scenario analyis and decision making.
