Electrical Circuits EEE 3. Cut-Set-3 : a. Elements Q31 and Q33 are +1 since the branches 1 and 3 are linked with cut-set-3 and are
also in the same orientation as that of cut-set-3.
b. Elements Q32 and Q35 are zero since the twigs 2 and 5 are not linked with cut-set-3
c. Elements Q34 is -1 since the branch 4 is linked with cut-set-3 but it’s orientation is
opposite to that of cut-set-3.
Thus we can now frame the fundamental cut-set matrix as shown below:
Now using this matrix the current equations can be written as below:
