Circuitikz not drawing anything

Question

I'm just learning circuitikz and I'm trying to draw just simple elements, such as :

\draw (0,0) to [V=$V$] (0,2);

And all I'm getting is the label (V) displayed, and not a voltage source.

I thought I might be doing something wrong, so I took some simple circuitikz code (from the circuitikz manual), and pasted it straight into my document (required some reformatting) and still got nothing. I'm defining circuitikz in my preamble and I'm not getting any errors. It may be a newb error, or even an installation problem (just installed tex live 2015), but I can't figure it out.

Answer 1

I took your code snippet and created a MWE, which works perfectly fine for me.

\documentclass{article}
\usepackage{circuitikz}

\begin{document}
    \begin{circuitikz}
        \draw
            (0,0) to [V=$V$] (0,2)
        ;
    \end{circuitikz}
\end{document}

Try updating your packages by going to the MiKTeX Update (Admin). (Just press the windows key and search for "update", it'll pop up.)
