Calculate the electrical currents i1,i2,i3,i4 in the circuit shown in Fig. 1 , see lecture\# 7 for details. Figure 1: A resistor network with two voltage sources, where V1=15V,V2=55V,r1=5,r2=10 ,r3=3,r4=6,r5=7,r6=9,r7=13,r8=78. The currents can be determined from the solution of the following system of linear equations (lecture\#7) (Eq. (1)): 2 [A]r1+r2+r4r20r4r2r2+r3+r5r500r5r5+r7+r8r7r40r7r4+r6+r7[x]i1i2i3i4=[b]V1V200 - Use the Jacobi iteration method carrying out seven iterations 1. Lecture's and seminar's codes can be used. - If you use a calculator write all steps. - If you use MATLAB , print your code or the list of commands you used. Print results for every iteration including residuals for each equation. - Use 'format short'. - Any MATLAB (1) codes from lectures and seminars can be used to solve this
