Question

USE A MATHLAB PROGRAM AND RUN IT FOR RHE FOLLOWING EJERCICE

Matab n eleclric circuits there is a very important formula wthere the POWER thl is dissipoled in a compenant i catulted The pewer farmalo for DC (direct or direct curren)is: P-IxY btco here var at ans apening on the date you hovt. ·P-1* V--ask for voltage (v) and current ) P-RYr-ask for resistance (R) and current C .P-vRask for vol tage (v) and resistance (R) ask tor voltage CV) and resistance Shous formulos in 4he menu-for the user ta choose which one they nt to use

Answer 1

MATLAB script

clc
clear
k=menu('Power formula for DC','P=I*V','R*I^2','P=V^2/R');
if k==1
I=input('Input current value');
V=input('Input voltage value');
P=I*V;
fprintf('Power is %g\n',P)
elseif k==2
I=input('Input current value');
R=input('Input resistance value');
P=I^2*R;
fprintf('Power is %g\n',P)
else
R=input('Input resistance value');
V=input('Input voltage value');
P=V^2/R;
fprintf('Power is %g\n',P)
end

Result after choosing P=V^2/R

Input resistance value2
Input voltage value7
Power is 24.5
