Question

In MATLAB graph:

Voltage = 5V

Resistance = 10 ohms

Current = 5A

The graphs must be scaled to show the plotted curves as large as possible. Label the axis with proper units.

the question cant be more clear, please if you dont understand pass it to someone else to be answer

Answer 1

MATLAB CODE

clc; %clear the command line
clear all; %clear the work space
close all; %closes all open matlab window
V=5; %Given Voltage Value
I=5; %Given Current Value
R=10; %Given Resistance Value
t=0:0.5:30; % Time vector for generating the voltage , Current and Resistance
for i=1:length(t)
voltage(i)=V; % Voltage values for 30 sec
Current(i)=I; % Current values for 30 sec
Resistance(i)=R; % Resistance values for 30 sec
end

%% Generating an individual graphs
figure() % Creates a figure
plot(t,voltage,'r') % Plotting Time on X axis and Voltage on y axis
title('Voltage Graph') % title of the graph
xlabel('Time(sec)') % x-axis label
ylabel('Voltage(V)') %y-axis label
axis([0 30 0 5.5]) % axis limit (x-axis limits followed by y-axis limits)
% Same procedure for plotting current and Resistance graphs
figure()
plot(t,Current,'b')
title('Current Graph')
xlabel('Time(sec)')
ylabel('Current(A)')
axis([0 30 0 5.5])
grid on
figure()
plot(t,Resistance,'g')
title('Resistance Graph')
xlabel('Time(sec)')
ylabel('Resistance(ohms)')
axis([0 30 0 10.5])
grid on

Voltage graph

Current graph

Resistance graph
