The unknown currents for the given voltages by using the inverse of the coefficient matrix.
Answer to Problem 67E
Explanation of Solution
Given information:
The currents
Where
Calculation:
The given system of equation is:
Convert the augmented matrix into the row-echelon form by gauss elimination method:
Firstly find the pivot in the first column and swap the third and the first row:
Eliminate the first column and find the pivot in the second column in the second row :
Eliminate the second column and make the pivot in the third column by dividing the third row by
Eliminate the third column:
Therefore, the solutions are
