Question

Use the circuit below to complete the given MATLAB script to plot the three voltages Vr, Vc and VL. Run MATLAB then pick an answer from the choices below that matches the MATLAB plot.

4 Ω j1Ο Ω Zr + Vr - ZL + VL - 1030° ν (+ VS Vc Zc -j12 Ω

MATLAB uncomplete script

clc; close all; clear all;

Mvs= 10;

Avs=30*pi/180;

[Xvs Yvs]=pol2cart(Avs, Mvs);

Vs=Xvs+j*Yvs;

% Impedances values

Zr=4; ZL=10j; Zc=-12j;

x=[real(Vr) real(Vc) real(VL)];

y=[imag(Vr) imag(Vc) imag(VL)];

V=x+j*y;

clr = lines(numel(x,y)); %# colors you want to

h=compass(V);

set(h, {'Color'},num2cell(clr,2), 'LineWidth',2)

u=abs(V);

v=phase(V)*180/pi;
