I assign the result of a Solve to the variable eq8. Then I attempt to use this result in the definition of a function as follows:

In[166]:= eq8 = Solve[eq7, {V1}]
Out[166]= {{V1 -> -1.02 (461.185 - 1. im)}}
In[177]:= Vstrom = eq8[[1, 1, 2]]
Out[177]= -1.02 (461.185 - 1. im)
current[im_] := N[Vstrom]

This does not work. With copy of Out[177] and paste it into N[] I find

N[-1.0200000000000002` (461.184642121376` - 1.` im)]

When eliminating these `character, my function work. This is cumbersome. How can I get rid of the ` characters?

current[im_] := N[Vstrom]

This does not work. With copy of Out[177] and paste it - instead of Vstrom - into N[] I find

current[im_] := N[-1.0200000000000002` (461.184642121376` - 1.` im)]

When eliminating these characters, my function works. Why can't I use the notation N[Vstrom]? After all, these -characters in the above number are just the spec. that the number shall have maschine accuracy. So why does the funktion not work with these characters present?
