Answer 1

PLOT A is the correct answer.

MATLAB CODE:

clc;

Mvs=10;

Avs=30*pi/180;

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

Vs=Xvs+j*Yvs;

%impedance values

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

%total equivalent impedance

Zeq=Zr+ZL+Zc;

%calculate current

It=Vs/Zeq;

Vr=It*Zr;

Vc=It*Zc;

VL=It*ZL;

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

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

V=x+j*y;

clr=lines(numel(x,y));

h=compass(V);

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

u=abs(V);

v=phase(V)*180/pi;

figure(1)

set(findobj(gcf,'type','text','-and','fontsize',10),'string')

legend({['V_r=',num2str(u(1));A;'theta_r=';num2str(v(1));'^o'],...

    ['V_c=',num2str(u(2));A;'theta_c=';num2str(v(2));'^o'],...

    ['V_L=',num2str(u(3));A;'theta_L=';num2str(v(3));'^o']},...
