Question

MATLAB computational tool MATLAB of course much more powerful than this and is a de facto standard inthe design implementati many ed technological appli particularl signal Our initial ll focus the soluti of a steady state ysis probl somrhing you should be abl to do Provid us with all by hand eacul varying degrees about the need for this majority of typical circuit of Typical Using mesh and node ataly is, analyze the cineait Rhowr below in Figure and sol these mesh and node the specified C2 rm2 Mesh 2 krads brbot RLC crcul example red output (any) specified frequency. Plot the steadywsute Eesh power delivered nge plot and the steady de voltages another plot A R2 and calculae is average value. Circuit Analysh node analysis solution: inspection of the reveals that of the cincuitnodes, if node is assigned node, other node voltages they are and the node only essertal voltage rode for modal analysis purpose. Writing this node equation yields

Explanation / Answer

clc
R1=input('Enter the value of R1 : ');
R2=input('Enter the value of R2 : ');
L1=input('Enter the value of L1 : ');
C1=input('Enter the value of C1 : ');
w=input('Enter the value of w : ');
Va=input('Enter the value of Va : ');
Vb=input('Enter the value of Vb : ');
A=[R2+j*w*L1 -R2 -j*w*L1;-R2 R1+R2 -R1;-j*w*L1 -R1 R1+j*w*L1+1/j*w*C1]
B=[Va;-Vb;0];
C=inv(A)*B

sample output

Enter the value of R1 : 1
Enter the value of R2 : 1
Enter the value of L1 : 1
Enter the value of C1 : 1
Enter the value of w : 1
Enter the value of Va : 10
Enter the value of Vb : 20
