Circuit diagram (TikZ)

Circuit symbols are standardised, and circuitikz draws them correctly. This is a simple RC low-pass filter with a labelled supply.

#What this example shows

• circuitikz, which supplies the electrical symbol set.

• Component values on every part.

• A correct ground symbol.

#A worked example

Open it, edit it, or copy the source below.

The source, which you can paste into a new diagram and edit:

\documentclass[border=6pt]{standalone}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}[american]
  \draw (0,0)
    to[V, l=$V_{in}$] (0,3)
    to[R, l=$R_1$, a=$10\,\mathrm{k}\Omega$] (3,3)
    to[C, l=$C_1$, a=$100\,\mathrm{nF}$] (3,0)
    -- (0,0);
  \draw (3,3) to[short, *-o] (5,3) node[right] {$V_{out}$};
  \draw (3,0) to[short, *-] (5,0) node[ground] {};
\end{circuitikz}
\end{document}

#Making it your own

• TikZ is disabled by default; an administrator turns it on.

• The american or european option changes the resistor symbol. Pick one and stay with it.

• Label component values, or the schematic documents topology only.
