In this very simple example if I write
R+iwL
where R is measured in Ohms, w in s^-1, L in H, I expect that the
result is given in Ohms.
Why it doesn't happen in Mathematica ? Ho can I do to handle in a
simple way those conversions ?
Thanks
Hi, Theodoro,
I do it this way, simple enough:
In[30]:= R := x*Ohm;
w := z*Hz;
L := y*H;
H = Ohm/Hz;
R + w*L // Simplify
Out[34]= Ohm (x + y z)
