EX:
A file called vidv.m contains the following code that is supposed to compute the
voltage across the nth resistor in a voltage divider:
y = find_v(Rvec,n)
% y = find_v(Rvec,n)
% Compute v-divider voltage across nth resistor
v_out = vtot*Rvec(n)/Rvec;
return
An example of how the function would be used for a circuit is as follows:
>> vs = 12;
>> v_2 = find_v(vs,[10e3, 20e3],2)
v_2 =
8.0000
Correct the errors in vdiv.m so it computes voltage dividers correctly.
SOL'N:
Corrections are shown in red below.
function y = vdiv(vtot,Rvec,n)
% y = vdiv(Rvec,n)
% Compute v-divider voltage across nth resistor
y = vtot*Rvec(n)/sum(Rvec);
return
end
