Hello, I am not very experienced in Mathematica and have the problem that N[...] will not be calculated in In[26].

Can anybody help a bit, please?

There is no In[25]. Please post the code in the question (not as an attachment) and indicate clearly what is the issue.

Below the table in the code there are 2 expressions with N[...] that will not be calculated. I need the solved complex number as result and not a complicated expression.

N[1/(1/Za + 1/Zb)] produces a complicated expression and not a number :( the same here N[1/(1/Za + 1/Zb) /. {Complex[u, v] :> Complex[u, -v]}] not a number is shown, but a complicated expression.

In[21]:= NumericQ[Za]

Out[21]= False

Numericizing it comes back as a non-number because it is not NumericQ.

Correction.
