Problem 1: Circuit Analysis For the electrical circuit shown at right, with resistance and voltage values as indicated below: Vi Ri R1 = 150 R3=100 Rs=150 Vi=30 V R2 = 250 R4 R3 R4 = 200 R2 Rs V2 = 60 V the following equations can be derived for the mesh currents* ia, ib, and i: *Note: the true' currents are equal to the mesh currents in the outer branches of the circuit, but must be calculated from the mesh currents for inner branches, e.g., the current downward in Rs is ib- ic 450 ia -100 ib-200 c30 100 ia500i150 ic 0 -200 ia 150 350 ic60 a) Write a script circuirtAnalysis.m to define the necessary arrays for this system of equations, and solve for values of the mesh currents. The values should be saved to variables i-a,-b, and i-c b) Using Kirchhoffs current law determine if the solution appear to be valid? (Complete this work on paper)
