vco lowpass etc. don't work. Circuitikz

Question

How come that circuitikz does not give me the vco I intend to build? See this code:

\documentclass[tikz, border=10pt, 12pt]{standalone}
\usepackage{circuitikz} 
\usepackage{verbatim}

\begin{document}
\begin{circuitikz}
\draw   (1,0) to[vco](5,0);
\end{circuitikz}
\end{document}

But when putting a "R" instead of "vco" it gives me a resistor. Why can't I use vco, lowpass etc? Thanks a lot

EDIT: When I copy+paste the .sty and .cls files from the circuitikz directory into the directory of my project it works. But when I paste the files into my ~/.texmf-var/tex/ dir, it does not work, even if the ksepath-command tells me that this is a directory Tex searches for. Why is that? This is actually another question, but I hope someone helps me anyway. Thanks

see the documentation: https://www.ctan.org/pkg/circuitikz?lang=de and search for vco. Or am I missing something (forgot some \usepackage etc.) — jjstcool, Jul 04 '15 at 16:42
I think the vco is quite new, as I didn't know this option (and I needed it some time ago), and it's not in my downloaded manual, but in the online manual. Probably, you do not have the newest version of circuittikz. For me, it also doesn't work. I guess this option just exists in the newest circuitikz version... — crateane, Jul 04 '15 at 17:04
yes, when I did it now again it said that nothing was upgraded — jjstcool, Jul 04 '15 at 17:32
this version always seems to be quite old: http://tex.stackexchange.com/a/55459/44467 — crateane, Jul 04 '15 at 17:34
So, from the link above, I got a solution on my PC (Ubuntu). I made apt-get remove texlive-base and then installed it with the installer from https://www.tug.org/texlive/acquire-netinstall.html Now the vco-symbol works ;) — crateane, Jul 04 '15 at 18:09
Ok I'll try. Need to eat first, I am getting hangry (hungry + angry):-) — jjstcool, Jul 04 '15 at 18:15
perhaps you have to run mktexlsr if you change something in the installation, but I'm not sure... — crateane, Jul 04 '15 at 18:37

The version of circuitikz distributed with debian might be quite old, as stated here. And the keyword vco just came into circuitikz with a quite new version, 0.4, which is probably not yet available in the debian repos.

So you could uninstall the "apt-get-version", and install "vanilla" TexLive (see https://www.tug.org/texlive/acquire-netinstall.html). Just download and extract the file install-tl-unx.tar.gz, and run the contained installer....

You added the "updating" tag to the question. As I understand it (https://tex.stackexchange.com/tags/updating/info), the tag is about questions concerning "How do I update my distribution?" and not about questions where the answer is "You need to update your used package/distribution/...". Maybe I'm wrong? But +1 for your answer! – Stephen Jul 04 '15 at 18:52
yes, probably you're right! – crateane Jul 04 '15 at 19:36

With standalone, use tikzpicture environment instead of circuitikz.

Circuitikz provides two vco: VCo and vco.

enter image description here

\documentclass[tikz,border=10pt,12pt]{standalone}
\usepackage{circuitikz} 
\begin{document}
\begin{tikzpicture}
\draw   (1,0) to[vco](5,0) node[right]{vco};
\draw   (1,2) to[lowpass](5,2) node[right]{lowpass};
\draw   (1,4) to[VCo](5,4) node[right]{VCo};
\end{tikzpicture}
\end{document}

this code does not compile for me. I mean the vco below, not the VCo. How can I install the latest package, since it seems to be very new? – jjstcool Jul 04 '15 at 17:07
@jjstcool MikTeX, TeXLive and MacTeX provide different update methods. – Paul Gaborit Jul 04 '15 at 17:11
I am using Debian and Kile (KDE). I tried to do this: http://www.volkerschatz.com/tex/tpacks.html but cannot find /etc/texmf/texmf.cnf on my system. – jjstcool Jul 04 '15 at 17:20
@PaulGaborit, how to replace the curve inside the circle as in vco with an $\epsilon$ ? In other words, how to make a diagram with circle and symbol inside? – Sigur Sep 18 '17 at 23:33
@Sigur With circuittikz? This seems impossible since this package only provides symbols used in electronics or logic... – Paul Gaborit Sep 18 '17 at 23:41
@PaulGaborit, well, I am editing a text and the guy used a scanned picture which contains a battery with plus/minus and above it exactly that circle with \epsilon. He is talking about continuous and alternate. Sorry, but I have no idea about circuits. – Sigur Sep 18 '17 at 23:45
@PaulGaborit, I discovered what I need: a symbol for a constant electromotive force with the E inside it. – Sigur Sep 19 '17 at 00:19

It is VCo and not vco

\documentclass[tikz, border=10pt, 12pt]{standalone}
\usepackage{pgf,tikz}
\usepackage{circuitikz} 
\usepackage{verbatim}

\begin{document}
\begin{circuitikz}
\draw   (1,0) to[VCo](5,0);
\end{circuitikz}
\end{document}

enter image description here

Edit

As the required symbol is new, you can manually update to the latest version (0.4) from CTAN website.

On Windows with MiKTEX 2.9, you can copy all files from the above link to your latex root and Refresh FNDB.

Then, try:

\documentclass{article}
\usepackage{circuitikz} 
\begin{document}
\begin{circuitikz}
\draw   (1,0) to[vco](5,0) node[right]{vco};
\draw   (1,2) to[lowpass](5,2) node[right]{lowpass};
\draw   (1,4) to[VCo](5,4) node[right]{VCo};
\end{circuitikz}
\end{document}

VCo and vco are not the same. – Paul Gaborit Jul 04 '15 at 16:56

I mean vco, not VCo, lowpass would have therefore been more appropriate for my example... – jjstcool Jul 04 '15 at 17:08

vco lowpass etc. don't work. Circuitikz
