    z1=4-3*j; z2=2+j; z3=1-2*j; % Io pass z3 z4=5*j; % USE source transform, transform the current to voltage %[x,y]=pol2cart(pi/2,12) %I=x+y*j I=12*j; ZS=z1; VS=I*ZS % voltage % we combine ZS with z2; z5=ZS+z2 % transform the voltage to current IS=VS/z5; % combine Z5 and Z4, Z6=z5*z4/(z5+z4) %therefore Z6 and Z3 is in parral combination %use current division Z=Z6+z3 Io=IS*Z6/Z X=[num2str(abs(Io)),'∠ ' ,num2str(angle(Io)*180/pi)]; disp(X) pp10.7

     

    current to voltage

     

    voltage--> current ,and get the combination impedance between z5 AND j5 , leading to Z6. 

    Z6 and z3 is in parralel, therefore ,you can use  current division
