Homework Equations
V=IR
The Attempt at a Solution
80i_1-50i_2-30i_3 = -120
-50i_1+100i_2-10i_3-25i_4 = 0.
-30i_1-10i_2+65i_3-20i_4 = 0.
-25i_2-20i_3+100i_4 = 0.
i_1=-4.18239492
i_2=-2.66455194
i_3=-2.71213323
i_4=-1.20856463
I used python to solve the matrix (using gauss elimination) and I am pretty sure I have done that bit correct (it was setting up the linear equations that I was unsure of if they were correct and how to explain my workings)
