Matlab Program
% This program determines the power dissipated by
% 8 ohm resistor and current supplied by the
% 10V source
%
% the program computes the loop currents, given
% the impedance matrix Z and voltage vector V
%
% Z is the impedance matrix
% V is the voltage vector
% initialize the matrix Z and vector V of equation
% ZI=V
Z = [26 -20 0;
-16 40 -6;
-4 -6 24];
V = [10 5 0]';
% solve for loop currents
I = inv(Z)*V;
% the power dissipation in 8 ohm resistor is P
P = 8*I(3)^2;
% print out the results
fprintf('Power dissipated in 8 ohm resistor is %8.2f Watts\n',P)
fprintf('Current in 10V source is %8.2f Amps\n',I(1))
diary
OUTPUT
Power dissipated in 8 ohm resistor is 0.44 Watts
Current in 10V source is 0.73 Amps
