I'd like to know if it is possible to place a current source that looks like the following:
-
1Yes. You can do it yourself elfsoft2000.com/projects/bipole.pdf or give me a couple of days. What exactly do you call this? – John Kormylo Aug 14 '13 at 20:24

Oh wow, thanks! It's just a 'Current Source'! – user968243 Aug 15 '13 at 2:41

I would like to add this to my collection, but I need to give it a name. I read that this symbol is more common in Europe, but Europe is big place, and we already have a European current source. I suppose I could give it an acronym (YAFCS) or something. – John Kormylo Aug 16 '13 at 1:30

Hi, well I'm from Australia where this source is sometimes used. Some datasheets also use it. I just called it 'Iring'. Curiously, how is it that you 'add it to your collection'? Is there someone where I can just save the component so Circuitikz remembers it? – user968243 Aug 16 '13 at 1:58

You can put the definition into a separate file and \input it in the header (sort of like \usepackage). BTW, isourcebr it is. – John Kormylo Aug 16 '13 at 14:34
