I'm trying to write this simple code, the right answer is 0.3 with an angle of 143.13, the answer that I'm getting is 0.5 with an angle of 90.76, any reason why I'm getting the wrong answer
syms C w R
V=150*exp(1i*pi/2)
Xc= 1/(1i*w*C)
Z=R+Xc
z=subs(Z,[C w R],[0.25*10^(-6) 10^4 300])
I=V./z

Hello Diana,
I ran the code, followed by
Im = double(abs(I))
Ia = double(angled(I))
and got the answer you were expecting. Hard to say what might have gone wrong.
By the way for a problem like this there is no need to use symbolic variables, only to immediately substitute in values. It's easier to not bother and start out with C = 0.25*10^(-6), w = 10^4 etc.
