Here is a short compilable example

\documentclass{article}
\usepackage{tikz}
\usepackage{circuitikz}

\begin{document}
    \begin{circuitikz}
        \draw node[ground]{} to [short,*-] (0,0) to [C] (0,2) to [short,-*] (0,2);
        \node[xshift=1.75cm](0,0){$ \leftarrow $ Start ground here};
    \end{circuitikz}
\end{document}

which produces

The question is: How do you draw the first line of the ground in the marked point? The CircuiTikZ documentation for the node ground does not define an anchor in that exact position.

Although I suspect this is a kind of XY problem, no, there is no provision (for now) for a tailless ground symbol. It is quite straightforward to define one, though:

\documentclass{article}
\usepackage[RPvoltages]{circuitikz}

\makeatletter
\pgf@circ@declareground{myground}{0.6}{0.4}{
    \pgfsetlinewidth{\ctikzvalof{monopoles/ground/thickness}\pgfstartlinewidth}
    \pgfpathmoveto{\pgfpoint{-.6\pgf@circ@res@step}{0pt}}
    \pgfpathlineto{\pgfpoint{.6\pgf@circ@res@step}{0pt}}
    \pgfpathmoveto{\pgfpoint{-.4\pgf@circ@res@step}{-0.2\pgf@circ@res@step}}
    \pgfpathlineto{\pgfpoint{.4\pgf@circ@res@step}{-0.2\pgf@circ@res@step}}
    \pgfpathmoveto{\pgfpoint{-.25\pgf@circ@res@step}{-0.4\pgf@circ@res@step}}
    \pgfpathlineto{\pgfpoint{.25\pgf@circ@res@step}{-0.4\pgf@circ@res@step}}
    \pgfusepath{draw}
}
\makeatother

\begin{document}
    \begin{circuitikz}
        \draw (0,0) node[ground]{} to [C, *-*] (0,2);
        \node[xshift=1.75cm](0,0){$ \leftarrow $ Start ground here};
        \draw (4,0) node[myground]{} to [C, *-*] (4,2);
    \end{circuitikz}
\end{document}

tailless ground

Note that I also simplified out your zero-length short.

  • It works like a charm. Now, the Vcc connection would have the same implementation to behave as this custom ground? I don't know how to read latex macros – Martín Jun 18 at 19:41
  • vcc is just an arrow, see in the manual. Since yesterday's update it is configurable, but no, it's not tailless either. You can substitute it with a simple arrows (see the manual for TikZ arrows) if you don't like it. But again, I am unsure why do you want it. If you look at the second tutorial in the manual, you can find a much better way to have the grounds (or Vcc) on the same line in a more flexible way. – Rmano Jun 18 at 20:01

    BTW, now this component (called tlground for tailless ground) is int the development version. Will be standard from 0.9.2 onward (due in a few days). – Rmano Jun 21 at 11:08

You can just shift the ground up a little, if you don't mind overlapping the tail.

\documentclass{standalone}
\usepackage{tikz}
\usepackage{circuitikz}

\newlength{\kludge}

\begin{document}
    \begin{circuitikz}
        \kludge=\ctikzvalof{monopoles/ground/width}\csname pgf@circ@Rlen\endcsname
        \draw (0,0) node[ground,yshift=1.2\kludge]{} to [C,*-*] (0,2);
        \node[right=0.5\kludge]{$ \leftarrow $ Start ground here};
    \end{circuitikz}
\end{document}
